Alright, today I decided to have one quick battle during the break I took - and something strange happened. I'm driving to attack the StuG and suddenly, I am driving in the opposite direction, the tank just turns around (and shows the surprised StuG its backside). If the StuG was a derp, I'd be so dead.
There was no lag, nothing. Is this some physics bug?
