This hasn't been an issue for players using the Vanilla version of the game based on feedback, up to now. I wonder if there are any other mods or overhauls running alongside the vehicles. One change we made helped reduce errors a lot for players running other mods because all of the vehicle storage containers went back to default sizes and stopped conflict there.
i do have a few mods running
bdubs vehicles, zombies plus ( modded to work with a19 plus many of my own additions), the new world order which is a overhaul that im making and currently has a error in the progression xml, fire arms expansion 3.1, weapons a19, snufkin custom zombies, dp power expansion and the mod in question
these are the errors given to me in the logs
