Instead of just unchecking one box, If I understand @DaWaterRat, since there are approximately 93 permade and not in world sims at the beginning of starting a new game with all the worlds, I would now have to go into each household and edit the neighborhood stories one at a time since this feature is turned on automatically. This would have to be done every 5 to 10 minutes of play or because the game generates townies to fill roles in the game. I would also need to go into each empty house/Apartment which is over 100 lots with all packs, and zero out the bedrooms and bathrooms as well.
I would like to play the game, not have to spend my time doing this. I don't have the luxury of having hours a day to play a game.
