Sorry to pile on questions, but I've got this one and your crystal cave mod installed and the added crystals aren't showing up as options to put in my lightsaber on the workbench. Did I install something wrong? The other mods I'm using are K1 Community Patch, JC's Cloaked Hybrid Robes, JC's Cloaked Party Robes, JC's Mandalorian Armor, Bendak alternative, BoS, Yavin 4, and Balanced Pazaak. I can't think of anything in those that would conflict with those item files, but maybe someone who knows more than me has a clue?
Edit: OK! Figured it out. This mod and Yavin 4 are mutually exclusive because Yavin 4 also modifies the crystal cave/lightsaber upgrades.
