I am using the PRC, Q, and a few other haks, (Tile-sets, place-able's, clothing, heads, creature overrides and a few items. The order is the created top hak, which has the Baseitem 2da, and the clothing 2das, the items, heads, clothing, and creature override models, the prcq_armory, the PRC haks, the Q haks the tile-sets haks, the Q tile-set hak, and the my place-able's.
I have searched through my haks, and the class-feat 2da is not in them, so there should be no overwrite there. The problem must then be in the scripting for the mod itself, otherwise I am at a loss for where it could be. Of course the mod itself could be corrupt, just not enough to be unplayable or unloadable in the toolset.
