Today, we had a few guests who came onto vent to get re gray listed as something has stopped them from being on the list, after further review, we re-gray listed them, it then turned out that the only guests with access are the ones which have been re gray listed, i am unsure if this is a permanent fix (i.e. they are still GL after server restart) as we have not restarted the server. I don't know if its the MC servers causing this or one of the plugins which have been updated over night to cause this.

Moved to the right issue tracker.
