The same error with my mod (Eternal Tales). Don't wanna open new issue because error is the same. Here's my crash log:
crash-2024-12-02_21.19.20-server.txt

[Nwago-Dev]

Having the same issue here with my mod (Endertech Infinity). I believe it's related to nether biomes in particular, as having toggled the generation off for my nether biome has stopped the crashing.

[ArkyFursblack]

Removing a big part of mod just for one another mod is not good idea I think.
