So what happened was I started this quest at level 90 restoration and got to the part where I have to stand in the light to gain the persons approval, But before I did step into the light I thought "I think I will leave this and get 100 restoration then come back!" Oh how this will cause problems.

I got to 100 restoration and came back to try and finish the quest only to find that as soon as I enter "The Midden - Dark" EVERYTHING lags! Then as I walk past a certain spot the game just freezes!

Entering The midden - Dark and wait for 24 hours seems to lower the lag but the game still freezes the moment I walk past a certain area.

Yes, I know, It was stupid of me to leave it. Not one of my best ideas...
