there's a thread for that.
i'm pretty sure it's where you last logged out your character. the zone, whether or not you died there, if you dc'd or crit errored before you were logged out, if the world server went down while your character was logged out in a weird place or whatever. believe it or not, i was told it's related to your computer specifically. try logging on from another computer to see if that works.
but yeah if your character is still stuck, just put in a ticket asking the gm to unstuck your character.
