I was having this problem from the get-go and I've never been able to fix it:
First of all, when in menus, the selected text continuously scrolls down - not game breaking but a huge annoyance. My character will relentlessly run to the backleft, effectively running in a circle - which is game breaking.
Is this a known problem with known solutions? I've already tried uninstalling and reinstalling the game, turning on and off keyboard control, but have had no luck. Please help, I really want to play
