Two seekers comes over and starts shooting at you for a good 3-4 minutes with nothing happening, Miraak just standing in the background. After that time they stop, but nothing really happens. I just sit there on my knees.
Edit: Also those Telvanni lifts arent working either. Could this be related to my bugs in Dawnguard? Like "cant enter soul cairn" had to use console. Moth priest wont finnish reading, etc.
