It seems that the mixer can now only hold just shy of 7 units of molten metal, so if you put more than that into the smelter it will deadlock because the mixer can’t take more of that metal, and can’t use it up without enough of the others. The smelter also now will process an entire stack in one go so even when I threw in 5 of the other metals first, then 30 iron, it sits there chewing on the iron until it’s all done, then the mixer can’t take it all at once. It used to do it one at a time so the mixer would keep consuming it as fast as the smelter would spit it out so I used to just add 10 of the other metals, then 30 iron and walk away for a while.
So how do you make this work effectively?
