Hello all, I had a quick question that google couldn't provide the answer for. I have my smeltery up and running, works fine. However, I was wondering if it is possible to switch the order of the molten ore that is inside. I've seen videos of others just clicking on it to switch the order around, yet that doesn't happen for me, so I'm a bit confused. Is this possible in the current version of hexxit?
