It seems that if you kill the Holy Inquisitor too quickly you won’t get the 6/6 Order guards killed. I had to reset by going down the stairs just to finish the quest. Maybe have another set of guards on the other side of the training ground so the stairs aren’t a necessity for quest completion?
With the spawn rates changed in the dungeons to compensate for shards, you now have to run the desert dungeon twice to complete the ghouls quest. Hoping that the value of mobs to be killed or spawn rates can be changed to bring the quest in line with what’s available.
