Biome registry "Unreferenced key" errors when used with other mods (Better Withered Mobs)
bug
Hi! First of all, incredible mod, easily one of my favorites. It truly captures that vanilla+ feel and blends seamlessly into the game. It honestly feels like an expansion of what the Wild Update could have been.
I wanted to report a compatibility issue that seems to involve WilderWild biome registration.
The problem started when I installed another mod (Better Withered Mobs). After that:
- I couldn’t load any existing worlds (Minecraft reported them as possibly corrupted)
- Safe mode didn’t help
- When I deleted all worlds and the game tried to open the "Create New World" screen, the game crashed
From the crash log, there are multiple errors like:
"Unreferenced key: ResourceKey[minecraft:worldgen/biome / wilderwild:...]"
This suggests that some WilderWild biomes are not being properly referenced or registered when other mods try to interact with them (in this case, during loot table modification).
Steps to reproduce:
- Install WilderWild (with its additional datapacks)
- Install Better Withered Mobs
- Launch the game
- Try to load a world or open world creation
Result:
- Worlds fail to load (marked as possibly corrupted)
- Creating a new world crashes the game
- Registry errors related to WilderWild biomes appear
Additional notes:
- WilderWild works fine on its own
- The crash disappears if Better Withered Mobs is removed
- Minecraft version: 1.21.11 (Fabric)
This might be related to how biome keys are exposed or registered for external access by other mods.
