Had several mods loaded and kept getting this crash. Tried removing one by one and found that it's only Fossils causing the crash. Removed all of the mods and just tried loading Fossils and LLibrary and it's still causing it. Tried newer versions of java and forge. Tried different versions of Fossils and LLibrary. Tried lowering my render distance down to 6. Any help would be great as this is one of my favorite mods and I don't like playing without it.
