Pathing Specific Pathing Issue in "Disco" area within "Old Sebilis"

[surj]

Today we were hunting in the "disco" area and camping in the area where Gruplinort spawns. Next thing we do is pull the "an iksar necromancer" from behind the door on the right in the hallway. Tank runs out to the open area where Gruplinort spawns, waits for the Iksar necromancer to come out the door...waiting...kills some mobs...waiting... an iksar necromancer come from the front entrance of "disco" down into our camp area with a massive train of mobs. Instead of coming through the door, it decided to run around the back and bring his friends for a picnic. The tank did not cast or hit the mob to aggro, but was just range aggro from opening the door. Not sure if that makes a difference either. Hope this bit of information helps to narrow down the pathing issues in Sebilis. Thank you Eunomia for the continual in-game assistance as well!
