I have successfully installed NRass and am following your suggestions for Story Progression.
I see this note:
Pregnancy: Allow Participation = False
Note: If one of your sims to become inactive is already pregnant, you will need to set an exception for them on the Sim level or else SP will terminate the pregnancy.
So if I understand that correctly, unless I have other mods installed, if my Sim is pregnant and I rotate out, it will cancel out the pregnancy. Correct?
What I specifically don't want is for a baby to be born while I am not actively playing the family
