Rule #1 - Come up with a good scenario that hopefully all will enjoy.

 

Rule #1a - Save often or suffer the ignominious loss of everything you have spent the better part of every waking hour on for the past week.

Good point, Pete. I always save often as I progress through the building of a scenario, and under separate filenames too so that I have a fallback if I screw something up. Consider this subsection Rule #1(a)(i).

It's ok though, only lost bout 30 groups or bases. It was the positioning that will take the most time to re-create.

 

It was really starting to come together when in a flash it was gone.

Ugh, thats too bad. Don't get discouraged. I'm really looking forward to a Maidhof scenario !
