Bunnymally Do you use mods, or are you willing to add a few? If so, please add NRaas ErrorTrap, Overwatch, Traveler, and MasterController. Descriptions are here:

Load the save, let the game clock run for a few sim-minutes, click the base camp's map tag, and select NRaas > MasterController > Town Options > Reset Everything. It may take a while to run, depending on the speed of your computer. When it's done, you'll get a notification. Let the game clock run for a few more sim-minutes, then send your sim home. Do NOT save when Traveler prompts you.
If that doesn't work, or you don't want to use mods, let me know.
