I installed Story Progression fine, and get lots of new story notifications - that bit seems to work! However, any of my own modifications dont seem to have any effect. I'm cool with Sims doing their own thing, but I just don't want them doing important things without me haha! I wanted to turn off aging, pregnancies, getting new jobs, and promotions for inactive Sims, kind of like Sims 2.
Basically, I don't like inactive Sims doing big milestones, and want to disable them. I recently downloaded Nraas Story Progression after being reccommended it on Reddit.
