Lanhern Firepride (S. Qeynos)
 

Last night there were 3-4 instances of this merchant NPC up. Not sure if this is just a simple "reboot" fix or if it is an actual bug.

Yep
 

i was going to make a new post about this, but since you already made one..

Location:
In Fireprides shop. Location is 190.05, -314.16, 3.44 in South Qeynos.

Problem:
Meera Lylon and 2 x Lanhern Firepride are in the exact same place. It's hard to select them individually with the mouse, and 2 identical npcs isn't good!

Fixed, will be in next patch.

!

man this bug has been around forever

Rejoice and be glad!
