This glitch, in itself, causes no real noticeable effects or issues. It seems to be purely graphical in nature as the NPC cannot be interacted with, but can be targeted.
I was leaving the area of the Shrine in T1 Emp RVR and rode my mount through the Order encampment beside the actual Warcamp. Suddenly, i saw the floating icon that marks a merchant hovering over my head. It took some few moments to realize I had another rider on my mount with me. I could target this person, but not interact otherwise. Unfortunately I was disconnected before I was able to experiment further.
