Hi, sorry to bump this extremely old topic, but I just want to officially document somewhere that I haven't done anything in regards to Ghastone yet as the full storyline isn't ready for the mysterious town's appearance, but when everything's all set in regards to the other saves involved in the storyline, I am going to use Porter to "Pack" the population of the United Kingdom, a world I downloaded from the Exchange and populated with StoryProgression's Immigration option, and then "Unpack" them in Ghastone, which "canonically" at this point would be called Midnight Hollow. After the disaster, the population of Midnight Hollow would canonically rename the world to Ghastone just before they collectively haul their Simmy butts off to the United Kingdom (simulated by mass deletion of what remains of the world's population), and then temporarily start a new save in the canonical version of Midnight Hollow to "Pack" the residents within it, then "Unpack" them all in Ghastone and delete the temporary Midnight Hollow save before continuing the storyline from there.
