The server I frequent is FL 2-11. I just found a tent which led me to drop my second gun so I could run to find a place to pitch and set it up for a food stash. I ran north into the woods where I knew I would find it, placed some items in it. Lounged for a moment in which I saw the loss of connection in the server. So I waited until it came back up and joined. My tent was gone and everything in it. So was my gun that I dropped. I'm obviously not asking that my stuff to be returned, just that I can trust a server to be persistent when it says it is.
Also, every bit of loot that I saw in the town I was just in had changed. So I know it wasn't just my stuff.
