Furnaces will stop operation when an inserter attempts to insert a item other than fuel and is different than the furnace currently contains.

I have been unsuccessful at reproducing the issue manually.

Bricks take 2 stone. There probably already was a stone in the input slot, so it can't insert an iron ore on top of that, so it can't finish creation. Also, the furnace has 'generic' inputs, where the item in the slot determines what's being created, so the inserter can't know it shouldn't insert the iron ore. I'm going to guess this will end up in 'not a bug'

Solution: don't mix inputs on furnaces, stick with coal and only one of the possible ores (at least until you know what you're doing and are aiming for mixed-input smelters, but that's advanced topics )

this/\

I looked at the save and boogie is right so not a bug just dont mix stone with other ores

You guys are correct. Sorry for the false report. Should have paid more attention to the situation.

I placed a miner too close to iron and was getting one on the belt every so often.

Thanks for the help and all the work you do on the game.
