Yeah there are bugs. I told my wife Aela to move from Whiterun to Lakeview manor. She went but couldn't get inside. She just stood outside right against the kitchen wall. It's like she knew she belonged in the kitchen but didn't know how to get in.
So, I told her I needed help and to follow me. She did, and I ran to the door with her right behind me. I went in she never entered. I came out and she was nowhere to be seen, and then I saw the graphic of her coming out of the house. I tried several times, even though I led her in and they'd show her coming back out, she never actually appeared inside. When released from following me, she went back to standing outside by kitchen wall.
And I tried adopting Lucia in Whiterun, but it would only let me move her into the Whiterun home. There was no option to move her to any other house including the manor I'd built and fully furnished. I upgraded the lab to kids room and moved her in thinking I could move her afterward. Aela automatically came back from standing outside Lakeview. I then went to ask Aela to move again, thinking Lucia would automatically go with her, but the moving dialog was gone. Lucia had no moving dialog either. And to top it off, Aela kept bytching that the house was to small and we needed a bigger one!!
