Well as you all know, Hearthfire allows you to adopt kids and bring them into your home. After building the small house in Lakeview and then adding the main hall I decided to try out the new adoption mechanic. I went to Honorhall and picked out a boy and then went to Windhelm to get the girl. So that left my character and two children living in this new estate along with the housecarl/steward. Well after 48 levels, I decided it was time to get my character married. Not that she couldn't handle the kids and house by herself but I wanted to see the unique dialog the father of the family would say. After finding a candidate a getting hitched, I had him move into the newly built mansion. But he doesn't seem to know the kids are even there, he only recognizes we're married, no options come up to ask him how the children are doing or the like. But, the boy talks about how Pa is going to take him hunting.
I think it has something to do with not being married
before adopting. If we adopted the kids together maybe he would recognize them but as of now he acts like they don't exist. I think it could be a bug in the scripting somewhere. The game probably assumes everyone will be married before they installed Hearthfire anyway so they didn't prepare for anyone having kids beforehand because it was impossible.
Not a gamebreaker for me, just want to know if it will prevent me from seeing any raids or ransom notices. So far in about a month or so of game time I've hand only one giant approach my house, things have been relatively quiet.
