This was on Pagle. Have noted what seems to be a layering problem carrying a guild member passenger in a flying passenger mount (the Sandstone Drake). As we transitioned between zones (from the Vale of Eternal Blossoms into the Valley of the Four Winds) my passenger and I got split into completely different layers. The passenger promptly fell out of the sky and died in a spot the spirit form could not reach and had to use a resurrection shrine. I could not personally cast resurrection because the passengers corpse was in a different layer and mass ressurection would not reach them. Apparently this is happening with some frequency as my deceased passenger observed another player falling to their death nearby.
