Hello. I'll try to get straight to the point. I've been playing Dawnguard DLC for the past few days and I've picked to fight on the Dawnguard's faction side. I've reached the mission Touching the Sky in which I am told to confront arch-curate Vyrthur. The problem is the actual boss fight, because I cannot progress past it. Vyrthur unfrozes a bunch of chaurus bugs that attack me, I kill them, then he sends a few frozen falmers on me, I kill those too, then Vyrthur says: "a good display, but your time is at an end." and this is were everything stops working properly. Vyrthur starts using magic to destroy chapel pillars, but that's about it. There are still some falmers frozen and I've seen a youtube video in which they are unfrozen by Vyrthur and the fight continues. Basically the boss fight scripting seems to get broken right after Vyrthur's "your time is at an end" comment. I have lots of mods installed, I haven't had problems in the previous quests before this one. I was hoping it was a mod issue, I disabled most of them but it didn't fix the problem. I fast traveled to other places and reloaded the chapel to be sure that mods were not interfering any longer, but still the same. Has anyone else experienced this sort of issue? is there a possible fix for it?
