The "Productivity limitation" startup setting doesn't actually DO anything, I'm running a K2-SE save and I went through each recipe and NONE of them changed productivity modules between toggling the "productivity limitation" setting(what's it supposed to do?), and the recipes that smelt from stacks of items into normal results instead of stacked results never have productivity in them. Is this intended?
Also, the modded bunch recipes get productivity(including the Deadlock Stacked versions in most cases), but the iron/copper bunch recipes don't.
