Flush Them Out Quest Area Is Broken

so basically, im aware this quest has plenty of bugs when it comes to it not counting for people but this is a new one for me at least and i cannot find a fix anywhere. Everytime i go Up the hill of the area to the sepulchur Every enemy (even the ones i can see down the hill) despawn untill i go back down the hill, there by making it Impossible to complete this quest. halp? EDIT; oh ffs, so basically the issue is if you have to gift of n’zoth You are phased out of that area (kinda stupid tbh) so you have to Complete that quest and remove the gift to fix it.
