I am unable to control my tank at times! He just goes off involuntary on a another route and the turret turns involuntary at times. Really spoiling my enjoyment of the game. Why is this happening?

I am experiencing my tank going in totally random directions that are not controlled by me. Like I am going forward and it will suddenly divert left or right. My turret moves as I fire so I miss or just continues rotate! My tank will go forward and even though I want it to stop, its continues forward!! Its spoiling my enjoyment of a great game. Are others having the same issue? Apologies, if this has already been raised but the more people that raise an issue similar to this, the more I feel confident, its the game messing around and not me?! Then hopefully it will get sorted. Sooo frustrating! :angry:
