I have just started using this mod to add more biome IDs, but whenever I make a new world, the generation is a gigantic blank void with nothing but one cloud in it.
It worked absolutely fine before, although I added it alongside Tropicraft. I also have aoa3 and biomes o' plenty, which may be conflicting

Also having this issue with default terrain generation.

same issue no matter the generation

It also may be because I have the lost cities as well

This same thing is occurring to me as well, and I do not have Lost Cities. The worlds I had generated beforehand are fine, but any new generation just does void. The issue is not Biomes O plenty nor AoA3 either as I have tested with that as well.

As is mentioned in #151 this is probably related to having JEID and NEID installed?
