Cave Prince Compat

Compatibility repairs for two custom R.E.P.O. levels on REPOLib 4: Underground Cave and BluePrince (Mt Holly).

Underground Cave

• Relinks the level's start room and modules when they are missing at registration (37 module references).
• Extraction points: creates the missing extraction-area/gross-up objects so extractions work, with a hidden renderer so the extraction countdown no longer throws.

BluePrince (Mt Holly)

BluePrince 1.3.2 was built for REPOLib 3. A small BepInEx preloader patcher (BepInEx/patchers) repairs BluePrince.dll at game start, before plugins load:

• Implements the Content.Bundle property that REPOLib 4 added. BluePrince's PrefabContent assets load again, so their network prefabs are registered: Workshop crafting works (Coin Purse + Lucky Rabbit's Foot = Lucky Purse).
• Repairs files modified by 1.0.0, which had made PrefabContent abstract (the type loaded, but crafting outputs could not spawn).
• Fixes two calls to changed game methods (cursed idol damage and discovery display).
• The original file is kept as BluePrince.dll.ctbak. Nothing is changed when the file is already compatible.

Underground Cave and BluePrince are not forced dependencies: install the map(s) you use.

Multiplayer

Every player must have this package and the same map mods.
