TS2 Players, What Did You Do With Darren Dreamer and Cassandra?

I usually have Darren & Cassandra marry, but I have also resurrected his late wife a few times.

I'm almost done playing all the families in Pleasantview, & will move on to Strangetown - but I have a question: How do you reset the towns with Ultimate Collection? I tried the old way of removing the neighborhood folder, but it didn't work. All I had was one less neighborhood. :(
