If you added new items in refpackageitem,pricepolicy and scrap, you probably added a wrong durability value. happened to me once.
so check refscrapofpackageitem

its already worked, but i dont know whats wrong now :D

i just enabled the 12D light armor items in npc and then nothing work, i disabled them and still dont work xD
