Hi NoOtaku, a couple things to try. Try disabling all game controller input in the options, to see if by chance it's related. Also, seems silly, but try disabling the RAM Cache as well. Finally, try hiding both the side bar and the game details, just in case they are related to the issue. None of this really makes sense, but I'm admittedly grasping at straws. Make the changes one at a time, so if the issue does go away, we know what might be causing the issue.
The other thing to try is to make sure that the latest betas haven't magically fixed the issue. You can enable the beta downloads in the Options as well. I'd suggest trying this first.
Thanks! Let me know how it goes.
