After the introduction of the new 0.58 update on 7/30 and wipe of server items, today I had placed 4 separate persistent items in a fairly hidden location. A barrel, a tent, a backpack, and two V3S vehicles. All had items stored within them. After the scheduled 12 hour restart of server Experimental US Northeast 01 I checked the location and found that all persistent storage items and their contents had survived the restart. I left the area and played for roughly 45 minutes and never logged out of the server. Upon returning to the location all storage containers were missing except for the 2 V3S vehicles. The tent, the oil drum, and the backpack were very spread out from one another and very well hidden in the forest. The liklihood that another player found all separate storage items, were able to transport them without the use of the nearby vehicles (that had all of their items intact) is highly unlikely. I believe that the persistent items were likely cleaned up by the server during normal server operation time.
