ModdedPurchaseKeeper
Fixes REPOLib-registered (modded) shop items being bought but not appearing in the level. Preserves modded purchase counts across REPOLib's per-level item re-registration.ModdedPurchaseKeeper
Fixes REPOLib-registered (modded) shop items being bought and charged but never appearing in the level — e.g. EMLGunPlus coil guns, and any other modded purchasable item.
If you've ever bought a modded weapon in the shop, watched it take your money, then loaded into the level to find it missing — this fixes that.
The bug
When you buy an item, the game records it in StatsManager.itemsPurchased, and at the start
of the next level ItemManager.GetPurchasedItems reads that list so the truck can respawn
what you own. But REPOLib re-registers its modded items on level transitions, and
StatsManager.AddItem resets itemsPurchased[name] = 0 for each one it registers — wiping
the purchase count of a modded item you just bought, before it can respawn. Vanilla items
never go through REPOLib's registration path, which is why only modded items disappear.
(Verified against EMLGunPlus coil guns on R.E.P.O. 0.4.4 / REPOLib 4.2.0.)
The fix
Instead of fighting REPOLib's re-registration, ModdedPurchaseKeeper keeps its own ledger of
what you actually bought (hooking StatsManager.ItemPurchase / SetItemPurchase) and
re-asserts the correct count in a prefix on ItemManager.GetPurchasedItems — the exact moment
the truck reads it. Whatever zeroed the value in between, it's correct when it matters. The
ledger is cleared on a genuine new-run reset (ResetAllStats), so purchases never leak
between runs, and it only ever raises a count back to what you paid for — it can't duplicate
items or interfere with consumables being used up.
No configuration. Load order is handled via a soft dependency on REPOLib.
Scope
Covers purchasable items (weapons, tools, carts, etc. — anything tracked by
itemsPurchased). Modded single-use upgrades use separate dictionaries and are out of scope.
Compatibility
- R.E.P.O. 0.4.x
- Requires REPOLib and BepInEx.
- Safe alongside other shop mods (MoreShopItems, etc.) — it only reads/writes purchase counts.
