So, I got married to Ysolda from Whiterun. everything went wel, we moved into my build home in falkreath (hearthfire) Adopted a girl.
then i started the dawnguard questline on the vampires side. finished the questline untill i got the quest: The gift in wich i have to turn my spouse into a vampire.
so went back to the house turned her into a vampire finished the quest everything alright? nope, since I returned the quest she completely disappeared....cant find her anywhere,

Help?

She's out pillaging with her vampire friends.

okay so, very weird but i found her by doing the treesap mission she's involved in...appeared she got captured by some bandits? o_O

Oh, ya, that happens in Hearthfire. Wait...they decided to pick on the Dovahpire and his vampiric waifu? *facepalm*

Perhaps I am mistaken, but aren't you supposed to receive a ransom note or something? I would certainly hope so anyway.
