Sorry for the huge bump, but after a long time of using this hack succesfully it stopped working. I have all the expansion and stuff packs, and I used the Apartment Life version (like you're supposed to, right?).

I'd propose a Sim to move in, they'd hug, and then the Sims would reset back to their places and nothing had happened. The save button was also greyed out, I would have to activate it again with the menu I have that optionally comes with the inSimenator.

I took the hack out, and lo and behold, moving in worked again.
I really loved this hack, so it kinda made me sad. ):
