Forge 32.0.108 , Minecraft 1.16.1

bluepower-1.16.1-0.5.216-alpha

Full log (immidiately took off server after it happened)
latest.log

P.S. if it'll help played All the mods 6 modpack (ver 0.28a)

if need something more (can even record it) just ask

Fixed in 1.16.2-0.5.218 will look at backporting to 1.16.1 soon if 1.16.2 continues to lack easy biome feature manipulation, as things stand is hard for modders to port to 1.16.2 without resorting to hacky methods.
