I'm going on an UBRS raid to get Rend's head. Nothing too unusual about that. So we head out to UBRS, enter the instance, and get told "You are not in this instance's group." Try and zone back out - no go. So we decide to log out and back in again in hopes that we'll wind up in the proper UBRS instance so we won't burn our Hearthstones when the game forcibly teleports us back to our bind point.
Log back in... and we're in - the Deadmines (?!).
Well...... almost.
I decide to try some fishing.
Unfortunately you can't fish off the edge of the world, it would seem.
