ETS 2 1.31 steam

Tell me how to solve the problem? Take the order in the world of truck, drive to the terminal, and the game can not synchronize with the world of truck. Just go straight to the last save, but the truck starts and doesn't move at all? Tried early AutoSave - the same trouble. Only option to cancel the order. By the way, well.d. crossing is no problem. Thanks in advance for the help
