Upon going to the End and killing the Ender Dragon, Minecraft crashes. I think it may have something to do with my More Swords Mod and More Enchantments Mod, although I'm not sure. My mods are More Enchatments, Mr.Crayfish's Furniture Mod, AnimationAPI (for Mutant Creatures), Mutant Creatures Mod, BiblioCraft, CustomNPCs, Forge GuiLib, In-game NBTEdit, Painting Selection Gui, Paintings++, Galacticraft and Galacticraft Mars, Modular Powersuits, MCCapes, Mekanism, MekanismTools, MicDoodle Core, More Swords Mod, Morph, Numina, and TMI. I am using Windows 7, version 1.6.4 on the MultiMC launcher.
