I went to the battle of miraak, everytime i called for a dragon and went on him, we just became ethreal and nothing happend. I killed the dragon and miraak got the soul, i lowered his health, killed the other dragon, he got the soul again. lowered his health and now he is stuck in the middle of the arena. By looking at walkthroughs, i saw that i need 5 black books, which i only have 2???? and when you read waking dreams it should make you ride his dragon n stuff but for me it right away puts me in the fight with him
EDIT: forgot to add in that when it puts me in the fight, it just starts, no dialog or anything.
