LeucotomyCore

Dedicated compatibility component for Leucotomy 3.1 ALPHA / Lethal Company v81, maintained by Thunderstore team 32 for the Leucotomy project.

WARNING: This mod is designed specifically for the Leucotomy 3.1 modpack. Do not install it standalone. Compatibility with other modpacks is not guaranteed.

Included component

LeucotomyCore 0.1.0 packages the existing, tested Leucotomy ConstellationDawnBridge 0.2.1 binary without recompilation or changes to its plugin GUID, Harmony owner or routing logic. The package version and the internal Bridge version intentionally differ.

The Bridge connects native Dawn moon purchases to the current LethalConstellations / LethalLevelLoader routing restrictions and configured moon prices. It preserves Dawn's original purchase conditions, checks the active constellation at confirmation, and keeps its hooks active for the application lifetime. Forbidden routes can still show a preview; confirmation must be refused before travel.

Reviewed versions

Component	Reviewed version
Lethal Company	v81
BepInExPack	5.4.2305
DawnLib	0.9.25
LethalLevelLoader	1.7.13
LethalConstellations	0.3.3

These dependencies are declared in the package manifest. The three content-framework versions above are checked by the Bridge at startup. If one differs, the Bridge logs Unsupported framework version; bridge NOT installed. and does not install its hooks. Dependency declarations do not guarantee that another mod or an update will preserve these exact versions; use the reviewed Leucotomy profile.

Installation in Leucotomy

Install through r2modman as a dependency of the approved Leucotomy profile. The binary retains the BepInEx plugin GUID leucotomy.compat.constellationsdawn and is logged as Leucotomy Constellations Dawn Bridge, internal version 0.2.1.

Existing development profiles may already contain a manually installed Leucotomy.ConstellationDawnBridge.dll. The pack maintainer must back up and remove that active local copy before installing the managed package. Keep exactly one active copy of this plugin. Renaming a duplicate to another .dll filename does not resolve the collision. Preserve a rollback outside the active plugin directory.

The package contains no modpack configuration files, so a standalone installation does not recreate Leucotomy's constellation assignments, prices or content.

Compatibility and known limitations

• Intended for the reviewed Leucotomy 3.1 configuration and framework versions only.
• Historical solo QA covered a forbidden cross-constellation confirmation, allowed routes and the basic one-time constellation fee behavior. A later solo pass covered all 12 public constellation switches and their first-entry fees. This is not a guarantee for every route, unlock state or discount.
• A forbidden moon may still display its route preview before confirmation is denied.
• Multiplayer / host-client compatibility has not been comprehensively verified.
• This component does not repair interiors, enemy spawning, Xen generation or unrelated shutdown problems.
• This release does not include RoutingObserver, ChatCommands, experimental bundles, Fiend MaxAlive guards, Moai filters or a new spawn system.

Future updates may add separately reviewed compatibility modules. No such modules are included in this initial release.
