Flipped a M1025 while driving in SP Game Master. The unit I was remote controlling fell into the void upon pressing X and getting out. The game immediately crashed.
Vehicles no longer work in the Game Master environment after this event. The issue persists beyond game restart. When I turn the wheel or switch on the engine the vehicle starts to slowly float in a seemingly random direction and I lose the ability to drive forward/backward and/or steer in either direction.
Sometimes one or multiple tires appear to clip through the terrain. This issue persists no matter the terrain surface or the vehicle. Moving the vehicle a few meters into the air and dropping it properly resets the vehicle's position on the terrain, but this only lasts until I try to drive it.
This problem does not occur in the tutorial, only in Game Master as far as I have tested.
(EDIT: I specified the Game Master mode but upon further testing it appears that the issue is tied to vehicles like the BTR, the logistics trucks, and the M1025, while some vehicles like the off-road I tested in the tutorial work fine.)
