I can see from your saves you have not corrupted the school enough as you can still use gas potions at assembly on Monday morning. So you have not enslaved the school.
This will lead to not visiting Mrs Simpson at night as there is content where the school needs to be enslaved that ties in to her content.
The residential wives are also not corrupted enough, so they will not be available to knock up at the hospital. Again the school corruption is linked to them via Principal's family. If the school corruption is not high enough, you cannot further corrupt Becky and Dana, and you need them to corrupt the wives.
The park moms need to see the pet play event with the nun Maria for them to show up at the knock somebody up at hospital. This is done from Utopia private room, visit to the park with the daughters in charge of their moms and then go to hospital to knock them up.
