I was playing my Sunset Valley save, following my sim Sian around town, and saw this outside of your apartment:
Yeah, three NPCs who apparently live there. I sent Sian on her way but staked out the apartment. Later I saw Miss Keaton, my family's maid, returning home.
Maybe the reason why no NPCs moved in before is that it took my game some time to generate more homeless after I had them run out of town. I think I'm going to move Sian's widowed grannie into the apartment so that she can harass, I mean, interact with the neighbors. :twisted:
