I play on steam with windows 10, mouse and keyboard. I drive my tractor around with three trailers. (this happens with anything on the trailers). I attach anything to the front of the tractor, it can't drive anymore and I have to reload save. Also, sometimes when I get out of the tractor its front wheels are bothe turned in L or R and it doesn't drive either. if the wheels are turned and it does let me drive, everything moves except the front wheels on the tractor which lag backwards through my trailers.
