Shattered Halls Executioner

I know about the floorplate and the debuff that's supposed to happen.. and It seems I need a character over 10 on lordaeron to report a bug, but I dont play or lordaeron.. so dont really know where else to go with this

The Problem:
Ran Shattered Halls 3 days in a row for the Trial of the N'aaru, but floorplate event did not work a single time after first boss, thus failing to complete quest

How it should work:
walking past the doorway of his room into the next should trigger a floorplate event that spawns the executioner.

How to reproduce:
i think id rather know how not to reproduce. daily reset makes it harder to test

if you can give any advice it would be nice
