I've just got Lakeview into good enough condition to move my family there, but when I talk to Ysolda to do the move, nothing goes as it should.

If I select Lakeview as a new home, Ysolda will go back to her normal routine from before the marriage, and the children will stay at Breezehome. Ysolda will still talk to me like I'm her husband, but will otherwise only move between the Whiterun market and her own house, never going anywhere near Lakeview or even Breezehome.

I also tried using Honeyside as a destination, in which case Ysolda does move there, but the children still get left behind. In either case, I get script errors that seem to be from Hearthfire:

I'm using the latest version of Skyrim, as well as the latest unofficial Hearthfire patch. I checked if the unofficial patch makes any changes to the script TIF__000C57F6, but it does not. How can I fix this?
