I've had no trouble adding new items in the form of weapons and shields in the past, but I've recently tried making some new misc items for a crafting mod and it's causing CTD's ever five or so times I mouse over them in the inventory. I know it's not anything to do with the code/plugin, I got no crashes before swapping the meshes out, so the only thing I can think of is that I'm doing something wrong with NifSkope that's causing the new meshes to occasionally kill the game when they're called up.

I'm familiar with the basics of nifskope, but I'm at a loss as to what I'm doing wrong this time.

Any help would be greatly appreciated.
