Strangerville Refresh

I never finished it, despite feeling I had an awesome setup for it, so I don't know what needs refreshing.
But I am glad we have rental homes now, because I do plan to return to Strangerville with a Photographer sim who has rented a house as a base for her desert photography. She will discover the weirdness going on there and I will finally finish this pack.

My Strangerville has Fox Mulder and Dana Scully living there in a nice military barracks and science lab, along with two aliens they found snooping about that might have some tie-in with whatever is happening to the town.

My approach was to have a team of sims work through the mystery together.
If there is a way to make it more enjoyable with several sims, I would like that.
