Describe the bug
Mod Compat issue -
Earth2Java mobs don't spawn in mushroom biomes when installed with Biome Makeover.
A user alerted me to this and I verified it.

E2J mobs still spawn in other biomes, but none in the mushroom fields.
My guess to why this is happening is that you have not migrated over to Fabric's new biome modification api (example here)

If you don't think that's the issue or you think it's something on our end, let me know, and I can do what I can!

If you have any mobs in the badlands, it's likely happening there as well.

To Reproduce
Install E2J fabric with Biome Makeover, look in affected biome.
