Just logged on today and some of my base is missing, only some if it... 2 walls, a container, 2 bedrolls, a tank, and a claim flag. Everything else is there, whats goin' on? Its close to the beach by Fernwood Farm and it is out of reach of the zombies and not a part of a permanent structure. I followed the guidelines and rules, so I don't think its that kind of issue.
If you had evidence of the player breaking server rules they could be banned. Without that evidence nothing can be done.
