As soon as I got married to Janessa, she flat out disapeared. Its been over a week and she hasn't appeared back at the drunken huntsman. Is there another way to find her? If not, is there another companion who is good at sneaking?

This is my first real bug in Skyrim (other than a dragon who wouldn't die - stayed at 0 health) so I guess I can't get too bugged, but jeeze, this has ruined my companion travels.

back in the tavern

Which tavern? The tavern where she originally came from, in Whiterun? She's not there.

Your house? Her house?

I don't own a house. If Jenassa owns one, that's news to me.

I'm having this very same problem with the Breton chick from The Hag's Cure alchemy shop in Markarth.

I lost her for a week, she disappeared right after we said the "I do's". Then a week later she reappeared in the Temple of Mara. I told her that we can live in my house in Whiterun, and we exited the Temple at almost the same time. As soon as Riften loaded, I got to see her jet off across the sky at the speed of sound, now she isn't anywhere...

Her former bed in the Hag's Cure remains empty and says it's unowned now, and she isn't appearing anywhere...

I wish I knew where to find her...

maybe shes cheating on you
