As it says on the tin. Seems like its a persistent problem
Infinite Falling loop Garrosh’ar Point in Jade Forest - Support / Customer Support - World of Warcraft Forums (blizzard.com)
and I have the same issue. Falling forever. Tried unstuck, still falling. On my hunter Jinzo - Moon Guard. Til never take random teleports from npcs.
If a GM could move my character i’d be very grateful. Heck, kill me if need be. I just want to stop falling so I can play her.
