for now disable all crafted weapons in the game later when crafting weapons add a 2 factor authentication.. when you select a craftable weapon you have to preview the weapon before you craft it making it so you cant bug it also this did give us some ideas like maybe new frames for existing weapons.. explosive bow bolts, burst fire shotguns, fully automatic scout rifles etc maybe this bug could become a features (within reason) maybe have these new frames on underused weapon types
