"Remnants of a Battle" info...

[Baphnedia]

Hi!  So a friend of mine, Thomas, and I play on the community server, Kobolds Hoard and after we first defeated the wormhole guardian (we did it together) almost a week ago, we've been getting a message every time we jump from one system to another on the server.  "There are remnants of a battle.  But nobody's here right now."  I'm struggling to figure out how to.. resolve this message and we think it might be somewhat of a bug, and have defeated the XWG several times since, and the message never clears.
