Where: Har'Akir, Temple of Anubis
When: several times in both servers
What: NPC (well, disciple of Anubis really) walk and die on the traps in the side corridors
Recreate: Fight in the two room adjacent to the entry point, open door to the corridors, find stacked corpses of Disciples of Anubis on active traps that likely tried to run and help their buddies and found peace eternal instead.
Ideas: trap faction bug?
I remember this being an issue for quite a long time, so I would be sure it has already been reported, but my search-fu gave me nothing.
