Simply by loading up the Nether and generating the appropriate biomes.

Additional information

No response

This seems to be caused by another mod adding features to our Nether biomes, but not in the correct order. It definitely doesn't occur with BOP alone anyway

I understand this has been marked as closed. but I've run into the same error. is there a way to decipher where the issue is originating? I've attempted a reload with all the mods that I know of that have made changes to nether biomes but its still persisting any time a new world is created.
