So this has been the reason I have been gone for so long. I will paste the crash report but first I wondered why my second option thing about if I want that better foliage mod, or conquest sound pack, and voxelmap doesn’t come up. I hooked yes on voxelmap, and I think that could maybe be why it crashes (I am on a mac), but I can not undo my hook because the option doesn’t pop up. Do you know how to get it back? Maybe it is is something with Java. Well, anyway, here is the crash report/error messages (this is only the last part of it):
