As of today, I already have 2 finished cars despawn while driving.

The first car was a fully assembled ADA 4x4 (packed with loot) on a dirt road.
Everything was ok, suddenly my passenger had a still picture, just sound and couldn't do anything anymore.
However, I drove a few meters until I could no longer interact with the car.
Since nothing worked we logged out. When we logged in, we stood at the spot on the dirt road where my buddy had the still image and the car with the whole loot had disappeared without a trace.

The second car was a gunter with 2 doors missing, otherwise everything was fine.
We drove over a curb in the parking lot of the right supermarket in Vysotovo and suddenly I had a black screen where only the dashboard displays could be seen and there was nothing I could do but log out.
My Buddy was still in the car, which was in the parking lot and saw me normally in the driver's seat but could no longer interact.
When I logged in again I stood in the parking lot of the left supermarket and ran to the spot in the other parking lot. I didn't see a car, not even my buddy.
However, he saw me and was still in the car until he also logged out because there was nothing else he could do.
He also spawned in the same place as me before. The car had disappeared without a trace.

We had no such problems with the cars last night.
We assume that this error was caused by today's hotfix.
