Poser DLC Dragonborn (The Elder Scrolls 5: Skyrim)

I encountered one problem in DLS Slayer. In the temple of Mirak when I play for example warrior, mage, assassin with a two-handed sword, assassin, mage, etc.
In General when I started to read the book black...(everyone knows what happened next) Mirak sat on Sarotra...dragon flew and Mirak were left to sit in the air at one point, I thought okay it will pass but not when I reached the final stage codelsa on Sarotra mirak I was infected with this. In short, I no it could not perform this quest and the leader of the Skaal died in vain. Can someone tell me the patch for this DLS?
