Supposedly it's not a terrablender issue according to them so idk ¯\_(ツ)_/¯

I forgot to mention that I am using terrablender, but yes I am, and I've been following this example from them here: https://github.com/Glitchfiend/TerraBlender/tree/TB-1.19.3-2.1.x/Example/Forge Would you need any other specific files from that for diagnosis?

For some reason, when generating my biome, none of the mobs that I put in there will ever spawn, though sometimes default vanilla animals I haven't added will. I've tried generating my biome in a single biome world and the mobs I desired spawned but it needs to work for a default world preset. This is the json file for my biome: https://gist.github.com/Phoenix-WB/e6499a5e5e660d5d4435262f32e61e41
