Hello. Instead of drilling mindlessly into your skulls about marrying Serana, I have a legitimate problem. So, I completed the Vampire questline. About the third time I had her as a follower, I tried to dismiss her in the Volkihar Cathedral. She then said that she would meet me at what I believe she said to be Darkfall Cave. Later on, I found her in the castle. I activated her, and thats where the main problem happened. I can no longer ask her to follow me, only to treat arrows with her blood. Why can't I tell her to follow me? Can this glitch be fixed? She is pretty powerful as a follower, and I don't want a glitch to force me to find another one. And NO, I am not interested in her as a wife.

Try going back a few saved games and not dismissing her?

I have never heard of this problem... hopefully those guys drooling over her will know a work around lol

Too late. I've already completed several quests, and leveled up. Something I don't want to repeat.

am I the only person with this problem?

It happened to me also. Idk how to fix it

Friend had this happen as well. If you have a save load it, if you don't, uninstall the DLC, save, reinstall, load that save. You'll have to redo whatever you lost.

Yeah you're pretty much outta luck. Try getting a different companion and dismissing them. FUS RO DAH her. Paralyze her just try whatever. Random stuff can trigger things...
