Server 3.3.5 X1 - Bugged purple rune in Blasted Lands

[En1gma]

The purple teleporter runes in the Blasted Lands takes the player to the peak of a hill. There are two ways to be teleported:

1- if you have the quest You are Rakh'likh, Demon, just talk to Deathly Usher (it's a ghostly apparition placed close to one of these purple runes) and it will teleport you instantly
2- if you don't have that quest, you just step on one of these runes and teleportation happens instantly

That's how it worked on the official server.
Please fix it.

This NPC takes you to the top of the mountain without these runes.

I know, I've already specified it, maybe you missed it. This npc only teleports those who have the quest.

The runes that are around this hill still serve to teleport you up if you step over them, without talking to that npc, as it was on the official server.
