Hi folks! I've been using the smelter frequently to make netherbrick for my rail line, and it's been having a few problems. Most importantly, items are not being sent to the chests on the ground level, they are getting stuck in the hoppers at the end of the line, before they go into the dropper. I know nothing about redstone, otherwise I'd try to chase down the source of the problem myself. If someone who knows more about it needs help troubleshooting I would be glad to lend a hand.
However, the aforementioned malfunction wouldn't be as much of a problem, but people seem to be abandoning their smelted items at the smelter. The chests at ground level are getting backed up, and with the malfunction, the furnaces aren't able to smelt properly because the hoppers below are full. Please make sure to retrieve your items, whether they are for your personal use or Fort Knox!
