expected the biome generating in the nether and not in the overworld

Additional Context:
Installed the mod after making the world

Never install new mods, particularly ones with biome generation, into an existing world. It will, 9 times out of 10, cause issues like this one. This is not the mods fault.

Could you send a screenshot of the biome in the overworld, @DaSentientToaster? I'd quite like to see it.
