Alright so, I was playing some Pass Time on the new map (pretty fun) and suddenly my mouse sort of broke free from the game and started showing the cursor while wildly spinning my view around. I alt-tabbed to attempt to fix it, which didn't work, so I tried to quit only to find that it wasn't registering any of my inputs. So I forced closed the game, booted it back up, and it won't let me choose anything on the main menu. I can double-click on the menu buttons and they get highlighted, but I can't actually pick any of them. My mouse and keyboard are working perfectly fine, and validating the game files didn't do anything. This is the strangest thing I've ever seen happen, I don't suppose anyone knows what's wrong?
