When I try to make a stirfry or a roast using ingredients that ive used before (lets say an eggplant) the game wont let me. It just makes a pan called "stir fry" but it has no hunger values and the ingredient just stays in my inventory completely untouched. Also, there are cases where im unable to even use some foods in stirfrys or roasts even when I should be able to. Ive many times cursed the fact that I cant cook rodent meat on a pan. I have 0 zero mods active and im running the newest patch.
