When I test the game in the Engine itself, the VehicleBody (the car) behaves normal, but when I export the game for Linux/Windows/HTML weird things start to happen. For example, if I try to turn right or left the wheel rotates, but the car still drives forward. And if drive over the edge of a start plane the car "floats" in the air, until the back wheels are also over the edge and then the car drops.
But those things happen only if I am exporting my game for Linux or Windows or as an HTML File. Is there anything I am missing here?
