Mirak ate a new mushroom. (The Elder Scrolls 5: Skyrim)

Going through Skyrim again on a new build and I have never had problems with Merak. Always everything went like clockwork - three times he was revived, then he's fucked. In this walkthrough the glitches began on arrival at the clearing of the Mirac - YY and remained seated on the dragon after arriving, I listened to the dialogue Mirak, and then he climbed off the dragon and started a fight. After losing health, Mirak is not transported to the center of the pool and moved to one of the dragon ( the second screen is on the tail ) flying over the field. Of course, I realized that this is a bug, but was wondering how it would end - called the dragon, which arrived and began to air dragon combat. As I expected, after the murder of two dragons, nothing happened, and the marker Merak disappeared from the map. Rolled back the save game, started a new one, but could only achieve a disembodied Mirak in a puddle, which didn't react on anything, even after the command Resurrect, he came to life for a second and once again fell into a stupor. Other dances with a tambourine also came to nothing resulted. There were options when Mirak just died without rebirth as a simple NPC and the quest was not counted. Beating the battle with Merak more than 10 times and never having achieved the normal ending, solved the problem this way in the beginning of the battle entered the command at the end of the quest Setstage dlc2mq06 580, there is a book and a message about the completion of the quest, then just kill Mirak and pick up his clothes. Is one piece, the dragons remain alive and they are enemies, and this makes it impossible to read the book and navigate around the map. Stored and will ship out this save - the dragons are gone and you can continue playing.
