In doing Firestorm Citadel, while talking to Vanaduke with his greeting message and dying from fire, the message will not disappear and you will be stuck, only to find yourself to either Quit/Logout/Return To Haven.
Even if you are revived, this has no effect on this bug.
That fire causes so many problems, it needs to be dummy fire or they need to put up a invisible wall like the one that keeps you on the party button on the roarmulus twins.
