Okay, a particularly weird bug; I had finished surviving the year and continued to play the game, and a couple or so days into spring, I tried cooking multiple chickens using the generic "cook any meat" option, but what I got was.. weird. Some of the returns were cooked chicken, but I also got "Cooked Meat" a couple of times out of I think 4 chickens, which had no data for what it did, and it had the steak sprite, but one was silver quality while the other was gold.
My pets would not eat it, I dared not try and cook it or eat it, thinking it was an error item that may mess things up if I did.
I promise I did not take any transmutation lessons in the game XD.
