Deathknight Quest don't work

[Weezzer]

A few quest from the Deathknight don't work.
So the quest where i must open the soulcave and kill the prisoner.
the soulcave don't open or the progressbar works and when its finished the prisoner is not free so i can't beat him to complette the quest.

The secound is when i must fly the big eye to scout the enemy.
The eye spawn but i can't fly it im just the Dk and i have the view from the eye, if i move the eye fade away and the view changed back to the normal view.
If i go to in GM mode i see the Eye following me -.-

The third problem is when must go to find the horeses, here i don't have the abillily to catch a hores and when i attack one of the horeses the begin to attack eachother, it looks very funny but has nothing to do with the quest :P

i hope someone can help me.
so thx to every one who help me
