Tested on 1.21.4, C2ME version 0.3.1.2+rc.1.0+1.21.4, Combat Nouveau version v21.4.0-1.21.4-Fabric

When both mods are together, attempting to enter the end dimension freeze / locks the game. Logs say something about a missing "the_end" biome, which makes little sense.

Disabling every config option in c2me does not stop this behaviour.

The linked issue suggests that this is probably not our fault. Gonna keep this issue open until they came to a conclusion.
