Working on wrapping up the Hunters Achievement for the Twilight Sea in Luclin on Cazic-Thule. Started about two weeks ago. Down to the hidden section in the north of the zone access via the underwater tunnel. Over the past few days, I've noticed the pathing NPCs in this portion of the zone just seemed to vanish. I went from static camp to static camp and those are fine, but all pathers are gone. Using a ranger, I started tracking by distance. Using the "/target" command, I can try to target a NPC such as "/target a_van" and I can target it. Then I can cast a spell and kill it, all while I can't see it, nor can it attack me. I believe there are a good 20-30 NPCs spawning below the terrain. The zone probably needs a reset.
