When driving the M1025 up a hill on grass/forest terrain, the car will stop at some point and roll back. (I did not try on Asphalt)
But then it won't accelerate anymore at all. Not foreward, not backward. The engine does not even respond actually.
Only fix is to stop and restart the engine.
I've been currently experiencing this on official server and can replicate on and on.
I waitet for the server to restart but that did not change a thing -_-
