So with the new patch came a new issue for me: I can't even patch in the first place. I've tried restarting my computer, but yielded no results, and I'm considering re-downloading the game. But before I do try that, I want to see if anyone knows how I could fix this. It's probably something simple and I'm just being silly, but I don't know what else to try. I really want to avoid re-downloading if possible. :/
