@cybergrrl - I have started saving all my families (moved out families too) to the bin so if I need to restart I can at least add the families back in....I have had so many restarts it is sad :) and I like the hair too...I think it came with an exchange downloaded Sim.
I moved towns with my family. I had downloaded a world called Sunnyville, which I really like, but then realized after I began playing that the empty lots were all small (most were 20x30) and would not fit my homes...off to Hidden Valley now. Waiting on gen 3 to be born. Almost have all of Gen 2 aged, paired up, and moved out.
