So im playing on the 0.6 the experimental SDL (dont know what that is xP ) and i had an NPC who had adamantite claws. He died and i could pick the claws up. This shouldnt happen already, i think, since the claws are an CBM modification.I can pick the claws up, wield them, and i cant use my hands like you normaly cant, but i cant unwield them and at the same time i can just drop them. So i think this is a bug of some sorts and if you need a better explanation feel free to tell me.
