While I was driving my V3S some wheels pristine, some worn, some damaged. While I was driving them up a hill on the road holding 'W' and 'SHIFT' for about 15 minutes they randomly broke, ALL OF THEM! After they broke the vehicle kept gliding forward despite the engine being off and no wheels. Luckily I could break the speed and step out, only to discover that the truck had disappeared behind my back!
EDIT: I found the truck again! I kept running up the road and found it! Wheels are missing still though :( I guess somehow my character teleported back some distance.
Also, everything that was in the truck is now gone as well.
