Uthgerd died (actually died, no question about it) in a dungeon during a quest, so I resurrected her, as I didn't have a save at a convenient location to me. She walked off, I finished the quest, and when I went back to Whiterun to get her, she was not at the Bannered Mare. So I waited. Still nothing.

I then tried teleporting to her, and it took me to a test room, which consisted of a four way corridor made up of checkered-pattern walls.

So, I reloaded outside of the test room, and teleported her to me. She spawned next to me, so I had her follow me, then I had her go home.

I checked Whiterun again, and she still wasn't there. Waited and then fast travelled out and back in, still nope.

Then, I tried spawning her at the Bannered Mare, right inside it, having her follow me, and then dismissing her. Went out and back in, still there, so I had her follow me to Markarth. All was seeming fine, until I dismissed her again.

Before checking if she had actually returned, I had spent two days in Markarth. Travelling back to Whiterun, she still wasn't there.

I luckily had no inventory items stored on her. I also checked the Hall of the Dead, but didn't find her body there after I had teleported her (I went to it while she was following me). I want to know, is there any way to completely fix her, or reset her state or whatever, so she acts normally, and doesn't require teleporting all the time? Or will I need to rewind 7 hours back to fix the problem?

Thanks.
