after the update, My other household sims keep having babies

After the update, my other household Sims keep having babies even though the household size limit is set to 8.

Every time I check the house, it’s full of newborns and the female Sims are always in labor again. But after the birth, there’s no baby anywhere!?

And somehow all the babies are the same gender too.

another one, I’ve been playing this family for generations with the Royal & Legacy pack, and ever since the update, every time I start playing this household, I get notifications saying  dynasty member has joined — one alert for each family member.
