Im stuck and i cant log out.

So while doing the argent crusade questline i got blow up when i handed in a quest (i have no idea what happened, something just exploded) and now im floating in the air while im dead. Is there any way i could unstuck myself other than logging out with alt+f4 and waiting in a queue for a long time because i encountered a bug?

type this in game chat:
/script RepopMe()

The above command usually automatically releases you when you're dead and unable to release. If this doesn't work, you can also try the website unstuck.
