Yesterday I found thew ADA 4x4 in Stary Jar with no attachment, so I dec ided to loot for the car parts.

I found the radiator and the battery so I attached them to the car. Now, because a week ago I experienced the same bug, I decided to enter the car at various stages of the process.
Once I entered it without any attachment, it didn't bounce off the ground. So I went over and found also the motor oil and one tyre. I entered again after I attached the wheel and added the motor oil, nothing happened.

Along with these two pieces, I also found some base building materials which I put in the car inventory (a generator, a cable reel, a truck battery, nails, 20 sheets metal, 3 ropes, 2 motor oils etc., all space in the car was full).

At this stage, after several times I tested the car by entering it only, and nothing happened (so it was fine), I entered one more time today in the car, to find out that it laid on the side and then bounced off the ground in the sky with me inside. at a certain point, I found myself out of the car, in a watery place in the sky (It looked like the top of the 3D model of the sky).
I then logged out of the server, and logged in waiting for the 90 seconds. Once I logged in, I was standing at the ground where the car was, and the car was not there anymore, disappeared.
