Biomes O' Plenty 2.1.0.1004
Forge 10.13.2.1224, 1230
Gregtech 5.05.13

I know that there's some kind of conflict between the Gregtech world generation and the Biomes O' Plenty world generation. If you remove either, the issue goes away entirely. I've already posted the same information on the IC2 forums.

@Adubbz close. Same as: #376
