So, I know this is kind of cheating, but I bought Conjure Baked Goods, and when I got the negative effect, I reloaded to not get the negative effect. I pressed it again, and, what do you know, I got the bad effect again. Then again. And again. And again. Maybe there's something I missed, otherwise that seems like a pretty big bug.
I'm not beginning to feel like a cookie god. I've always felt like one, because I AM one.
