I was Just flying around in a new world in amazement with this mod and EnhancedBiomes together's World Gen . Looks wonderful ,but All of a sudden the chunks stopped Generating ,and I pressed F3+A and it did nothing as it usually starts chunks back generating so I tried F3+S Then and still nothing ,but then MC stopped responding and crashed with this crash log here http://pastebin.com/XmZedaXV

Hi Crunk. Thanks for reporting the crash. It looks like you had the EB Fen biome enabled, and unfortunately, that's one of the biomes that isn't currently supported yet by RTG. Take a look at this issue for more details: #218
