Hello devs,
if you found a V3S on this persistance Server and the V3S was crashed in/on a wall so the V3S is unable to escape from the wall (the car stuck on the wall) the car is useless. And more no more V3S spawn. So in the end the Server has no car to use.
If it is like this (on our Server it is the issue) you could remove all V3S from DayZ, there is no different.
