I just chose the eldest daughter to take over the house, but when i chose her, she immediately came with the status "not married, 6 kids" and on the family tree page, it had the option of a new generation.

I thought it might be the 30th generation bug, since it was the old version and the daughter would be the 31st generation, but i downloaded the new version, and she's still in her 20s, not married with 6 kids (that don't appear in the house, nor in the family tree)

What happened? How can i fix it?

I'm not sure if i ruined my chances or not, because what i did was i went to new generation, and since it gave me the same kids to choose from (the daughter and her siblings) i chose her again. Then, since i had the same problem, i went to new generation again, and her 6 random kids showed up, and i chose one of these. Since i had the same problem i went back to new generation (which had the same 6 as the last time) and i chose her again. However, i still have the same problem.

I worry that this new daughter won't get a marriage proposal because she technically has 6 kids.
