I received land and built Heljarchen Hall, loaded it with children's stuff, and practically maxed it out. I then went back to Breezehome and spoke to Aela about the kids. She said Breezehome was fine but we needed a bigger place for the kids. In the dialog I selected I said we should move to a new home (no mention of the name of the home). She said she'll see me there, but didn't leave.
Getting frustrated, I did some more quests, and lo and behold, the Jarl of Windhelm offered me Hjerim for purchase (again). Since I had already purchased it years ago, I decided to do it again to see what happens. Once furnished, including children's stuff (these were offered in the steward's dialog for the first time), I returned to Breezehome and talked to Aela.
This time the dialog for moving to Hjerim by name was there but asking 'how the kids were' was not. If I said we should move to Hjerim, Aela left but the kids remained in Breezehome. The dialog for moving to Heljarchen Hall was there but only as 'I have a new home you'd like' which has been there all along.
So, how do I get both Aela and the kids to move, either to Hjerim or to Heljarchen Hall or anywhere?
Or am I just going to have to leave them in Breezehome?
