Well, I finished all of the requirements for the first town and moved my Sim to the next through the phone interaction, got the town set up, saved... Then realized that the second town's day is set to Week 1, Day 1 at 8:00 am. It's my first time moving a Sim that way through the phone to a separate town, so perhaps I messed something up when editing Appaloosa Plains to put in the lots I needed.
