A Sedan I found was working great at first with only slight desync issues. After 10-15 minutes of driving I parked it inside of a red barn while searching for a tire. I removed the spark plug so it couldn't be stolen easily. After 20 minutes I came back and changed the tire and replaced the spark plug. When I tried to reverse it out of the barn there was unbearable rubberbanding. It took me ~5 minutes just to get it out of the barn. I hoped it was tied to the barn and once I was out it would calm down. It did not. The speed and sound of the engine behaved normally, I reached some 40 or 50 kph but I was constantly rubberbanding back. The actual speed I was moving with seemed on par with a running survivor. I removed all 4 tires and put them back but that didn't help. I logged out for the night.
On the next day the car was still where I left it. I got in and the rubberbanding was the same. It was somehow tied to that specific car. It was in a buggy state. I am pretty sure the server restarted or crashed in the ~15 hours I didn't play.
Happened on DayZ Underground server which is always highly populated / full.
