If all you want to do is add Bluewater Sims you only need to delete Bluewater then add it back in. The delete option will come up if there is more than one shopping district so just add one to Pleasantview. The same goes for Downtown.
Never thought of that! I'll try it right away.
That saves my Pleasantview then. But I have even more questions! My Strangetown is filled with ghost characters. There's about 800 of them in the folder & I've never even played that hood. It was my hood for all the stray unwanted sims which I (stupidly) sometimes even transfered through the lot bin. But I love the way I made the neighbourhood look so I'd like to have it in the newly installed game as well. So my question is basically if there's a way to copy only the terrain with houses and decor into a new game, but not the characters. Before copying I could move the Strangetown people into the sim bin & then copy the folder, but I don't know which one, or if that's even possible. I know about terrain surgery, but that doesn't help me with the houses & decor.
