this may be a load order issue, but i cannot track down how to fix this error. i have read a good bit about the issues with leather and tribal start and such but not sure if this is dealing with that. here are a couple of examples of the log it gives me, but there are ones for numerous items within the mod, mostly dealing with headgear and apparel. i have two with a reference to dark elves, but i think thats forgotten realms mod.
