First time this happened, but I just switched around resource packs before playing. Also updated 7 mods:
Amethyst Equipment, Emerald Equipment, Obsidian Equipment, Alaska Native craft, Copper Equipment, MC Dungeon Armors, and Weapons. Now crashes when I try to open the equipment screen.

Should be the same as #53

Disabled Amethyst Eq, Emerald Eq, Obsidian Eq, and Copper Eq., still crashes. Disabled Alaska Native Craft, no change.
Disabled MC D Weapons, crash stopped. Reverted to older version, and sent an issue to MC as well.
