We got the same problems on our server, i dont know how to fix it. Some tents are saved, some are not. But vehicles are definetely NOT stored. After the server restarts, there are always the same vehicles at their spawns, always the same vehicles missing. Some Vehicles contain loot (always the same). I dont know if thats normal or not. Plus: The UAZ spawning at Altar has 10 RGO Grenades in its gear. I dont think that they are included in DayZ. We didnt set up the server ourselves, but someone (actual server owner) set it up for us. I know its a common bug, but maybe there is some common solution or error source? Maybe its just badly configured.
