As of Legion Remix’s start, the mobs in Black temple no longer path around in any logical way, instead running in erratic and jagged patterns. This wouldn’t be an* (How did I not notice this typo for multiple weeks??) issue, if it didn’t also include Akama, who - instead of running to the black temple door and opening the path to Illidan, ran back to the entrance of the instance and in random circles therein until I left and re-entered the instance.
He then respawned in the council room, and - upon being spoken to again, eventually janked his way to the door and opened it as normal.
I can only assume the most recent patch broke something in the map data, whatever it is that the mobs use to determine the best path to any specific point.
Edit: This seems to be affecting more than just Black Temple, so I’ve edited the post title to reflect this.
My Icecrown Citadel run was less exciting but I did notice some interesting choices made by the nerubians immediately prior to Sindragosa, despite their task of ‘reach the center of the room’ being almost as simple as it comes.
Edit 2: Seems to be impacting a number of Legacy Dungeons as well - was very noticeable during Warlords of Draenor Timewalking - especially in Auchindoun.
Edit 3: In the last week (10/29/25) I’ve noticed this issue in most forms of Legacy instances, from old Dungeons, to Battlegrounds, even to Scenarios. Stratholme is nearly impossible to complete reliably due to the waves of ghouls and geists getting stuck behind the gate in the Slaughterhouse.
The sheer vast reach of the issue leads me to believe the problem isn’t with the mobs themselves, but the map navmesh - like some kind of script went wrong around Lemix launch. Thread title updated to reflect this thought, but on the off-chance we get a blue post in here, I’ll update it accordingly.
As of 12/2/2025 this bug has been fixed. Thank you!
