With the new pack the autonomy of sims in the household seems really out of wack.
My child sim will not go to school. certainly if you switch sims for a bit. The action just cancels. In the end the school calls and even then they won't go.
Now it happened that the sim is set to be at school by the game, while he is still standing in the room. But the school icon is yellow, indicating that he is late. When I click on it, I get a pop up if I want to cancel him AT school and send him home.
While he is still at home. It's a mess.
As soon as a small business is open it disrupts all the autonomy and actions of everyone in the household.
I also had this with another sim who I tried repeatedly to send to grief counseling. Anything not business related is very hard to do for other sims in the household.
But the school thing is probably the most annoying.
In one case I had to travel to another lot and then send him to school. Else he just won't leave.
I'm not using any mods or CC.
They were already removed, cache emptied and the game was repaired because of other bugs. I have all packs, save a few kits.
