I've just had this issue pop up on a multiplayer mission I was flying, at some point during the flight the rudder attempted to go full left deflection without any commanded input (I even unbound all my rudder controls / axis and this issue still occurred). I wasn't able to find a solution and had to quit out of the mission. I've got a track file however I can't upload it here as the file is too large so you can find a link to it here: https://drive.google.com/file/d/18PHdqiE-WVobpOflJx0VdEwGbxtdfiiM/view?usp=sharing
