I'm sorry if I'm doing this reply/ post wrong (it's been ages since i've posted anything on EA/ sims forums), but I wanted to add a me too. I currently have 2 Izzy's, 2 mannequins (different clothing), and an Emily in my agency building. I have one sim working at the agency and another in the club. the coworkers at those places, my sims, the above mentioned extras, and an occasional sim i retired are the only people I'm seeing. I don't know if the game is reading the area as full or if the mannequins/ Izzys/Emily are messing up the area, or both. the second izzy showed up and started talking to the agency boss, then stopped talking when my sim chatted with the boss, then Izzy 2 stayed there, not moving. that was a few days ago. I can't remember if that is true for the other izzy or emily. i do remember the first one was a mannequin, cause I kept thinking a person's sim may not have fully loaded and the game glitched, then I realized the skirt was one I had gotten earlier from izzy.
My player ID is 1003455132186. hopefully someone will figure out what's going on and fix this.
