When i am editing my map, my camera slowly rotates despite no keys being pressed. Any idea how i can stop this? Ok i figured it out. There were two xbox controllers connected and it was causing the rotation.

Hi ShotgunHR, Good to hear you got it fixed, the Xbox controllers seem to have too much movement in the thumbsticks without actually moving them causing this issue. I will mark this question as resolved for now, let us know if you have any further issues. Thanks!
