I am making my first track at the moment, but when I try to test it the gameplay is almost always in slowmotion. When I load my track I can test it regularly but when I go back to the editor and try to test it again it's always slowmotion.
I also encountered double speed gameplay when I alt+tab in and out of the game, or when I switch from game to the steam/uplay overlay few times in a row when I am in a conversation.

There is no bug report since the game doesn't crash. Anybody any idea's to solve this?
