I left a plaguefall +12, after group disbanded, upon leaving the dungeon by the entrance portal i appeared on a flight path mount heading in a straight line. I proceeded to crash through the ground/mountains of maldraxxus heading towards oribos (ended up way underneath oribos it got to the point where the camera stopped tracking/following my character who ended up disappearing into the horizon.
Upon triggering the stuck character service i logged back in to find my self still on the same mount but heading from orgrimmar gates through the barrens towards the west of kalimdor and im now above the veiled sea with no fatigue bar (im guessing something to do with flight path mounts)
