This bug only happens once in a while, but it is really annoying.
What happens is when I’m fighting in a very small room (i.e. Barradin’s Vault), Phase Retreat has a chance to teleport me under the map! Once there, I get stuck under water with combat mode still on, so I can’t even teleport back. I have to deconnect and log in once again.
Very annoying, especially during a boss battle
