BaconFixer

Fixes for big Lethal Company modpacks, in one mod that works in any pack.
Needs no other mod · Each fix turns itself off when its mod isn't installed · Not everyone in the lobby needs it

Fixes for modded content look at what the content is built from, not at its name, so they also work for mods that aren't listed here.

Updating from 1.x? Game Rules and the terminal extras are now their own mods: BaconGameRules and BaconTerminal. Install them to keep those features. Your settings carry over.

How each fix works

Each entry says what goes wrong, why, and how to see it yourself. Click one to open it. Versions are the ones tested on game v81. If a mod has been updated since, its problem may already be gone.

To compare, disable BaconFixer in your mod manager, launch and follow the test, then enable it and repeat. Log lines are in BepInEx/LogOutput.log in your profile.

loaforcsSoundAPI 2.0.13, and any mod that makes sound clips on worker threads: crashes when quitting

• Affects: SoundAPI's sound packs, such as LethalResonance 4.7.8 with its 968 sounds. SoundAPI makes their clips on 16 threads at once.
• Why: Unity keeps a list of every loaded sound and changes it without a lock, so only the main thread should make or release sound clips. When two threads change it at once, the list can end up pointing at freed memory. Nothing goes wrong right away, but the game can crash later, mostly when you quit, while Unity cleans up sound clips. BaconFixer makes those worker-thread calls take turns. Calls on the main thread are unchanged.
• Cost: Taking turns loads those sounds one at a time. In testing, LethalResonance's sounds took 5.1 seconds to load instead of 0.6 with no other mods, and 5.2 seconds instead of 2.7 in a big modpack. This happens once, while the game starts.
• Test: This depends on timing, so it can't be triggered on demand. It was seen in a profile with only SoundAPI, LethalResonance and their libraries: the game crashed on quit, and Unity's crash report showed no mod in the stack. Unity's debug symbols name the function as SoundManager::DisposeSound, called from AudioClip::Cleanup. With BaconFixer the log has AudioThreadFix: sound clips are being made on worker threads, so they now take turns.

loaforcsSoundAPI 2.0.13: sound packs with sounds for mods you don't have

• Affects: Any sound pack that replaces sounds from a mod that isn't installed, such as LethalResonance 4.7.8's FacilityMeltdown sounds.
• Why: A pack names another mod's sounds through mappings such as #FacilityMeltdown:warning_voice, which that mod defines. When the mod isn't installed, SoundAPI logs errors and drops the whole replacer file, so the file's other sounds are lost too. Just before SoundAPI reads a pack's replacer files, BaconFixer gives each missing mapping an empty entry. Those sounds stay as they are, and the rest of the file loads.
• Test: Launch with LethalResonance and without FacilityMeltdown. Without BaconFixer the log has 2 fail(s) while loading for meltdown.json, and Mapping: '#FacilityMeltdown:warning_voice' has not been found. With it those lines are gone, and the log has SoundPackFix: with the pack's name and the missing mappings.

RuntimeIcons 0.3.3: icons take up RAM twice

• Affects: Icon images that mods ship in a RuntimeIcons folder, such as the 797 icons in RuntimeIcons_BetterRotations 1.2.21.
• Why: RuntimeIcons loads all of them when the game starts, and Unity keeps a copy of each image in RAM after sending it to the graphics card. Nothing reads that copy again, and the game's own item icons don't keep one either. BaconFixer loads the icons without it, so they look the same and use about 270 MB less RAM with RuntimeIcons_BetterRotations.
• Test: Launch to the main menu. With BaconFixer the log has IconMemoryFix: with the number of icons and the RAM saved. In a round, the icons in your inventory look the same as without it.

MrovLib 0.4.15, shown by TerminalFormatter 0.3.9: $0 store prices

• Affects: LethalLevelLoader unlockables, such as items from Farming and Cooking Mod by MelanieMelicious, and Magic sphere from Wesley's Moons.
• Why: MrovLib reads the price from the item's info node, which is often $0. BaconFixer uses the real price from the buy node.
• Test: Host a lobby and type store in the terminal. Without BaconFixer these items show $0. With it they show their real price, and the log has Fixed store price for 'Magic sphere': $140.

Any mod that looks for DunGen in the game's code: load errors

• Affects: Mods built before the game moved DunGen out of Assembly-CSharp, such as loaforcsSoundAPI.LethalCompany 1.0.2.
• Why: They still look for DunGen inside Assembly-CSharp, but the game moved it to DunGen.dll. In SoundAPI, its dungeon name condition throws during AudioSource.Play, which interrupts ambient sounds. BaconFixer forwards those types to DunGen.dll in memory, and game files on disk are not changed.
• Test: Land on a moon. Without BaconFixer the log has RoundManagerPatch::Reporting(). Error: System.TypeLoadException. With it that error is gone, and the log has Forwarding 133 DunGen types from Assembly-CSharp to DunGen.dll.

DunGenReferenceFixer 0.0.1: loading crash

• Why: Its native hook rewrites a Unity function, MonoManager::GetMonoClassWithAssemblyName, on every call with no lock, so two loading threads can collide and crash the game. BaconFixer's forwarders answer the same lookups, so that mod isn't needed. Remove it if you have it, because BaconFixer can't turn its hook off.
• Test: This can't be triggered on demand. It was seen once in 51 launches, as an access violation at UnityPlayer.dll+0x7842E0, the function it hooks. If your log has Patched MonoManager::GetMonoClassWithAssemblyName(), the hook is still active.

LethalModDataLib 1.2.2: mod data not registering

• Affects: Plugins that load after any plugin that failed to load, such as WesleysInteriorShenanigans inside Wesley's Interiors 5.0.19.
• Why: It loops over every plugin, and a failed plugin aborts the loop, so plugins after it never register their mod data. BaconFixer skips failed plugins and carries on.
• Test: Launch to the main menu with both installed. Without BaconFixer the log has a NullReferenceException from ModDataAttributeCollector. With it the log has ModDataFix: scanned N plugin(s), skipped 1 that failed to load.

Any mod: duplicate network prefab errors

• Affects: Mods whose bundles ship the same prefab, such as Gastank in Wesley's Interiors 5.0.19 and Wesley's Moons 7.0.18.
• Why: Netcode keeps the first copy and logs an error for the others. BaconFixer keeps the same result without the error.
• Test: Launch to the main menu. Without BaconFixer the log has NetworkPrefab (Gastank) has a duplicate GlobalObjectIdHash source entry value of: 298664861!. With it the log has Skipped duplicate network prefab 'Gastank' (hash 298664861).

Any mod that looks up types by name: terminal stutter

• Affects: Mods that call HarmonyX's AccessTools.TypeByName, such as TerminalUtils 0.0.18 and WeatherRegistry 0.8.8.
• Why: That call can scan every type in every assembly, which takes a while in a big pack. BaconFixer caches the results. A type that isn't found yet is looked up again once another mod's assembly loads, so a mod can still find a mod that loads after it.
• Test: In a big pack, type moons or store for the first time after launching. Without BaconFixer it stalls for 1-2 seconds the first time. With it there is no stall.

Any mod's scrap without a scan node: can't be scanned

• Affects: Modded scrap made without a scan node, such as the glasses from Farming and Cooking Mod 1.6.1.
• Why: The game's scan only finds items with a scan node, and it logs an error each time such an item's value is set. BaconFixer gives these items a scan node like the game's own scrap, so scanning shows their name and value. It only changes your screen, so other players don't need BaconFixer for it.
• Test: Have such an item nearby, such as a glass on the ship, and scan. Without BaconFixer it doesn't show up, and the log has Scan node is missing for item!: GlassOfBloodPrefab(Clone). With it the item shows with its value, and the log has ScanNodeFix: with its name.

Chameleon 2.4.6: manor windows and mineshaft caves in modded interiors

• Affects: Interiors built from the manor's or the mineshaft's parts, such as Spooky Manor and Atlantean Citadel from Wesley's Interiors 5.0.19.
• Why: Chameleon only sets up the manor's fake windows when the interior is the vanilla manor, and only restyles the mineshaft's cave rock in the mineshaft. In other interiors the windows always show the default pasture view and stay on when the power goes out, and the rock looks the same on every moon. When an interior has those windows or that rock, BaconFixer runs Chameleon's setup for them there too, so they follow its window and cave lists and PowerOffWindows. Pieces that mix that rock with another material keep their look, because Chameleon only changes a piece's main material.
• Test: Land on a moon with its own window or cave list, such as Rend for windows or Berunah for caves, when one of these interiors generates. Without BaconFixer the windows show the default view and the rock looks the same as anywhere else. With them the windows show that moon's view, the rock follows the moon, and the log has ChameleonSupport: with the interior's name.

Chameleon 2.4.6: door lights and snow on modded moons

• Why: The light behind the entrance doors only has colours for vanilla moons. Some moons also use the snow flag for sand footprints, such as Etern, so Chameleon treats them as snowy. BaconFixer picks the door light's colour from the moon's cave type in Chameleon's lists, and doesn't count a moon with desert or mesa caves as snowy.
• Test: Land on a modded moon in clear weather that's in one of Chameleon's cave lists, such as an ice moon, and look at the light behind the main entrance door. Without BaconFixer every modded moon has the same default colour. With it the colour follows the moon, such as grey on ice moons.

ImmersiveEntrance 1.1.3: no door portals on modded moons

• Affects: Modded moons and interiors, such as those in Wesley's Moons 7.0.18.
• Why: ImmersiveEntrance was tuned on vanilla moons. It looks for the plane behind the outside door in a few set places, and most modded moons keep it beside the door, so it drops the portals on both sides. Many modded entrances are also turned around from their door. The mod places its screen from the entrance, then moves it to the nearest wall and floor, so the screen can face away from you, sit too high or show beside the door. BaconFixer also looks beside the door for the plane, and on modded moons and interiors it fits the screen to the door itself. Vanilla moons, and doors the mod's author placed by hand, keep the mod's own placement.
• Test: Land on a modded moon such as Repress and hold E on the main entrance. Without BaconFixer you can't see through the door, and the log has Failed to spawn main entrance door portal. With it you can see through from both sides, and the log has Successfully linked main entrance portals.

DawnLib 0.9.27 with DestroyItemInSlotFix 1.0.0: items destroyed wrongly

• Affects: Anything that destroys an item in a slot you aren't holding, such as GeneralImprovements' UnlockDoorsFromInventory.
• Why: Both mods fix the same function, and DestroyItemInSlotFix changes the code DawnLib looks for, so DawnLib's fix stops halfway. That leaves the carry weight step reading the item in your hands instead of the one being destroyed. It takes off the wrong weight, or throws an error if your hands are empty. BaconFixer removes DestroyItemInSlotFix's patch, because DawnLib's covers the same thing, so DawnLib's fix can finish. Without DawnLib, DestroyItemInSlotFix stays as it is.
• Test: With UnlockDoorsFromInventory on and your hands empty, click a locked door with a key in your inventory. Without BaconFixer the door opens, the log has a NullReferenceException from DestroyItemInSlot, and the key stays in its slot with no icon. With it the key is used up, and the log has DestroyItemFix.

FacilityMeltdown 2.7.5: meltdown never starts

• Affects: Packs with enemies DawnLib doesn't know, such as Mirage 1.29.1's copy of the Masked.
• Why: When the apparatus is pulled, FacilityMeltdown picks the enemies that can spawn. For an enemy DawnLib doesn't know, it warns that the enemy won't spawn, then reads the enemy's DawnLib info anyway. That error stops the meltdown. BaconFixer leaves that enemy out, as the warning says.
• Test: Land on a moon and pull the apparatus. Without BaconFixer the log has a NullReferenceException from MeltdownHandler, later MeltdownHandler was disabled without starting a meltdown, and no explosion comes. With it the log has Spawning a ... during the meltdown sequence, and the explosion comes when the timer ends.

Base game v81, EnemyAI: error spam from enemies off the nav mesh

• Affects: Any enemy, mostly Red Locust Bees, which logged 819 of these errors in one round.
• Why: When an enemy is off the nav mesh, the game skips moving it and logs an error on every AI tick. BaconFixer skips the same step without the error, and logs once per enemy type.
• Test: This depends on where an enemy spawns. Without BaconFixer the log repeats Agent 'Red Locust Bees' #0: Agent not on nav mesh when trying to set destination. With it the log has one OffNavMeshLogFix line for that enemy.

Any mod, Unity particles: warning spam from sub-emitters with a stop action

• Affects: Any mod's particle effect that plays another one as a sub-emitter. Rain did it most: Wesley's Weathers' Hurricane and Forsaken rain and the Sub Systems interior's indoor rain logged Sub-emitters may not use stop actions. The Stop action will not be executed. 3,835 times in one landing.
• Why: Unity never runs a sub-emitter's stop action (destroy, disable or callback), but warns every time the effect plays. BaconFixer sets those stop actions to none after each scene loads and each level generates, which changes nothing but the log, and logs the effects it changed.
• Test: Land in rain with Wesley's Weathers, or in Sub Systems. Without BaconFixer the log fills with Sub-emitters may not use stop actions. With it the log has a SubEmitterStopFix line naming the effects, and none of the warnings.

Base game v81, RoundManager: dark interiors

• Why: An interior can destroy a light after the game has built its light list. The loop that switches lights then throws, so later lights keep their old state and part of the building can stay dark. BaconFixer removes destroyed lights from the list before each step.
• Test: This needs an interior that destroys a light, and most don't. Without BaconFixer the log has a NullReferenceException with RoundManager+<turnOnLights> in its stack. With it that error is gone.

BloodVFX 1.1.1: a blown-apart player's head seems to vanish, and the teleporter can't beam it up

• Affects: BloodVFX's gib deaths, where a dead player is blown apart and only their head is left as an item to carry back.
• Why: The game puts a non-scrap, one-handed item you pick up into the utility slot, and scrolling the hotbar never reaches that slot. Switch to another item and the head seems gone, though you still carry it. A head is carried like a body, so BaconFixer keeps it out of the utility slot and it goes into a normal hotbar slot. The ship teleporter beams up a dead player's ragdoll, and there's none, so it beamed up nothing. BaconFixer puts that player's head on the teleporter pad, the way the game does with a ragdoll, unless someone holds it.
• Test: Have a crewmate blown apart by a mine. Pick up their head: without BaconFixer it goes into the utility slot, next to the hotbar, and switching away hides it. With it, it takes a hotbar slot. Then put the radar on that crewmate and press the teleporter: the head lands on the pad, and the log has GibHeadFix: beamed <name>'s head up to the ship.

SolidLib 1.2.1: no outside music on any moon

• Affects: Every moon, with SolidLib installed, which Surfaced needs.
• Why: SolidLib replaces the game's code that plays music outside, so a moon can bring its own. Its copy reads a value the game made private in v81, so it throws every time and nothing plays. BaconFixer takes SolidLib's patch off, and on a moon that brings its own music through SolidLib, that moon's songs stand in for the game's while the game picks one.
• Test: Land and stay outside until the music would start. Without BaconFixer the log has FieldAccessException: Field 'SoundManager:timeSincePlayingLastMusic' is inaccessible. With it the music plays, and the log has OutsideMusicFix: took off SolidLib's outside music patch.

ImmersiveVisor 1.0.1: errors whenever an enemy with no eye is hit

• Affects: Any enemy without an eye point, such as Surfaced's Urchin, hit by a player or by another monster.
• Why: ImmersiveVisor puts a blood splat on the visor at the hit enemy's eye. With no eye, its patch throws, and since hits come through a network message, that message stops partway. BaconFixer skips the splat for those enemies, which never got one anyway.
• Test: With Surfaced's monsters on a moon, let an Eyeless Dog or a shovel hit an Urchin. Without BaconFixer the log has NullReferenceException with ImmersiveVisor.Patches.EnemyAIPatch.HitEnemyPatch in its stack, then Unhandled RPC exception!. With it those are gone, and the log has VisorEyeFix: ImmersiveVisor skips its blood splat for enemies with no eye at startup.

Base game v81: settings stop refreshing when the Escape menu closes

• Why: When the settings refresh, as when the Escape menu closes, the game reads the key each keybind is on right now. A keybind with no key active, such as one set to a gamepad or mouse button that isn't plugged in, has none, so it throws, and the settings listed after it aren't refreshed. BaconFixer shows that keybind's own text instead.
• Test: Bind an action to a gamepad button, unplug the gamepad, and close the Escape menu. Without BaconFixer the log has an ArgumentOutOfRangeException with SettingsOption.SetBindingToCurrentSetting in its stack. With it that error is gone.

Interactive Terminal API 1.3.3: one key press moves the cursor twice in terminal menus

• Affects: Menus made with Interactive Terminal API, such as Lategame Upgrades' store (lgu in the terminal).
• Why: When W or S goes down, the menu moves the cursor and starts repeating, every 0.1 s while the key is held. The first repeat comes after only 0.1 s, and a normal key press often lasts that long, so one press can move twice. On the store's first menu, which has only Shared Upgrades and Individual Upgrades, two moves land the cursor back where it started. In longer lists it skips a line. BaconFixer makes a held key wait 0.35 s before the first repeat, like a keyboard does. The repeats after that keep the menu's own pace.
• Test: Type lgu in the terminal and tap W a few times. Without BaconFixer the cursor sometimes stays where it was or jumps back. With it, each tap moves one line, and the log has TerminalKeyRepeatFix: a held key waits 0.35 s before it repeats.

Limits

ImmersiveEntrance still has no portals in a few places. Art Gallery's door is set against the room's solid wall and fades in and out with distance, so there's no doorway to see through. Galetry has no main entrance, and some moons, such as Duckstroid-14 and Acidir, have an older door. The doors still work normally, and the mod logs Failed to link main entrance portals.

Different prefabs that share a hash still spawn as the first one registered, because a real fix needs every player's game to agree. BaconFixer logs a warning for these, such as Network hash 3155849242 is shared by 'GASteelDoorMapModel' and 'SteelDoorMapModel2'.

Two log messages remain. DawnLib can log Couldn't match DestroyItemInSlot while loading, before BaconFixer has removed the patch that causes it. WesleysInteriorShenanigans, inside Wesley's Interiors, warns that it could not be instantiated. It was built for an older game version and stays off on purpose.
