Just wanting to know why you chose to remove Brejik special stuff from his loots and if you made similar choices with other loots ?
You can't unfortunately unless you go edit the UTI's yourself. He should've put the regular loot in their pack inventory and had the visual stuff as non-droppable. Alas, I'm working on my own NPC Overhaul for both games privately to allay these problems. I suggest you do the same.
