I am probably doing something wrong, but when I pipe charcoal into an automatic crafting table, put it in with a philosopher stone (without usage bar) and set it to make coal, the wooden pipe on the other side will not extract coal to be made into coal dust. I have no idea if im just a noob or this is a bug. Why won't this work?
