Issue Description:

(Please provide screenshots if neccessary/possible. Images can be dragged & dropped into this window.) Minecraft crashes upon generating a world with RTG.

The crash report looks like this:

probably because I installed JEID which added the support for more biome IDs but RTG can't recognize them.

Steps to reproduce the issue: (If it's easily reproducible.)

1. install RTG and JEID, along with many other mods that adds a lot of biomes (Biomes of Plenty and Traverse for example)
2. generate a world with RTG
3. the game crashes
