I do not know if this has happend to anyone else or just me or if this is old. But I just had an invite only session and I drove to my tank I had in pegasus and drove alittle with it and then it got destroyed and after it got destroyed I got a new one and went back to the place and I also drove my car there the tank spawned. And when I called my mechanic for a car when I was going to get the new tank (It was a far road to go, I needed my vehicle) and when I drove back to the new tank...My old parked car was still there. There was two of my cars..
Also, when I came back for my vehicle I couldn't enter it because it wasn't my personal vehicle anymore. Perhaps if another guy was sitting in it, it would become his. This is happening like the old duplications glitches before.
