Same shit here. Tried to repair a UAZ twice this day. The first one we had repaired half when the server restarts and after loggin back in it was totally screwed again. I thought we had bad luck with the server because our tent we placed before the server restart wasn't there anymore too. So we changed the server and collected half the parts, repaired what we had at this time and went searching for parts again. On our way back with the last parts the server did a unexpected restart and by the time we were back at the UAZ, it was again totally screwed. I hit save 3 or 4 times before leaving the UAZ after the first repair. But i didnt help.... 5 hours of gameplay for nothing...
