I've noticed when I leave my guild town that I get something that says "Dungeon Queueing" next to my HP bar. It doesn't really seem to do anything, besides make it so when I try to go back in to my guild town, it says that I'm in a party queue and cannot. This status appears to persist indefinitely until I log out and back in.
Any idea why this happens, and what I can do to prevent it? It's a little annoying.
