Adventure slot stuck with inactive player for more than 12h

[Drusek]

8h period doesn;t work. I have invited a player to adventure but he went offline after that. More than 12h have passed now and the slot is still not free and grayed out with the player avatar.

Check your outbox in the ingame mail window, as far as I understand it, this should force a check on expired invite etc
