Actually this topic gave me an idea.
When you want to craft, say, a P250 and you don't have Low Quality Metal on you, but you DO have metal fragments, why not make it automatically craft LQM for you and increase the crafting time accordingly? That might simplify things a bit, although it's more of a polishing touch and shouldn't have much priority, cause I want that freakin procedural map generation NAAAOOOO!!
yeah, I would like that to. There was even a thread suggesting this system a while ago, the OP called it "sub-crafting" if I remember correctly
