The Source Of The Recent Dupe Which Is Now Fixed (Patreon)

So you may have heard rumors of a recent dupe. I have been trying to locate the source of the dupe quite hard and I eventually discovered the likely source here in a video hiding in plain sight- it is public but was difficult to find on youtube:

So far as I can tell the dupe is now inactive - it is difficult to ever be entirely 100% sure when a dupe is fixed for various practical reasons.

I'm posting this mainly because it may that patreons can apply this method successfully in other areas of the game.

On a related note here is another powerful npc exploit in retail wow -https://us.forums.blizzard.com/en/wow/t/call-lilian-bugged/1912903

The poster is credible and clearly bugged out this powerful npc. However when I attempted to repeat the exploit there was no obvious way to glitch the npc out of the area. The exploit could not have been fixed in such a short timeframe after it was posted. So it seems there is a trigger here for a potentially game-breaking exploit we do not yet know. If you can figure it out you may have something game-breaking to yourself.
