Im not sure how this works but maybe someone can figure out what happened, I was in the "Last Stand of the Zandalari" LFR and I walked through the door, when I did I got a wow critical error message and it kicked me offline, then I started back in and when I loaded up, it kicked me offline again before it got into the game but the load bar was full(it said Disconnected from server), then I signed in again and got into the game but I was in Lei Shen's chamber and everyone in the LFR could see me in there on the map, and was asking how I did it, the chamber was empty but maybe someone could figure out how this was done and use this glitch in other places as well.
