So on my PS4 I have this problem.
When I press the L2 button to zoom in my aim, the tank turns to the left. Only intermittent, but happens several times per match.
When it does happen, if I keep L2 held down, the tank keeps rotating to the left until I release L2.
Is this a game bug? Or a control pad with a bad connection? (Don't find any probs using that button with other games)
