Over the last few days, we’ve been working to address the issue of disappearing PvP vendors, with mixed results.
Today, to temporarily address the issue, we’ve created copies of each of the vendors, and we have placed them on the 2nd floors of the Shrine of Seven Stars for the Alliance and the Shrine of Two Moons for the Horde.
So unserious with todays devs that they couldn’t even adress the issue for a few NPCs, that they had to locate them another place. Today’s WoW in a bubble, quickfix… so sad.
I would guess that the reason to flimmering and dissapearing for those NPC is somewhere inbetween that wall and two zones coliding/bordering eachother. Somewhere in that code you will most likely find the issue.
I think the issue here lies between layering code of WoW Classic and Cross realm code of Pandaria itself. Not only PvP vendors had this issue, but even flight master in Valley of four winds where 1000 steps ladder entrance is located. As soon as you enter from the ladder flight master appears.
Since they might allready fired those who did layering code in 2018 and those who did crossrealm code in 2011-2012 are long gone the outsourced coders from India with the help of A"I" might messed something up in this spaghetti code.
