The first time I noticed this, there was a partial aluminum ore (lidite, or something like that?) in one of the "input" slots. It mostly wasn't an issue as I could use the rest of the slots. (Although when using all 3 slots at once, it ate 2 of my aluminum, only got 1) Thing is, it eventually tried processing the partial ore, and outputted a partial aluminum, effectively breaking the smelter permanently.
While I have no clue what you would need to do to fix this kind of bug, could we get maybe temporary workaround? Maybe a keybind that will reset the state of whatever platform we'r
