add sim to family
make them talk to you
as a family member, you will never lose them forever as they step through the sim zone and turn invisible
one time i was in my house in san myshuno and i saw a very talented sim playing guitar for change far below my apartment in a park... i was zooming far far away with my camera from where I was.... anyway she stopped playing and started to disappear so I quickly clicked on her and picked some option about talking to her..... then she disappeared.... 5 seconds later she appeared in my apartment to fulfill the command ... I was amazed.... now I use this technique often....today I zoomed far away....saw a sim I wanted to talk to..... clicked talk.... and then I went there
