Maybe this is a server issue but I have a Vilayer public server. I just shut down the server so I could change the name and other text and when it restarted the items I left on the ground (items were in an ammo can and a backpack), the fireplace, and the truck were both gone. The items have disappeared during the 4 hour reset also.
I thought the persistence was working except for tents?
My server: Evil Chickens (213.231.140.49:2302)
I will also send a help ticket to Vilayer.
