So I was going about my business, just finished smelting a few hundred iron, then when I go to make some nails I go to click the feed button and it is grated out. Not only was the feed button grayed out but so was the little eye in the top right. I checked my other stations and it is the same thing with all of them. I can use the ones that don't use fuel but the eye thing is still gray for those too. I left and came back, replaced them, and even checked if I had my lighter. Anything I can do? NEVERMIND I needed wood
