I took out my Strangetown and Pleasantview and placed them in a different folder and have recently put them back in the Neighborhood folder but they are missing lots and families are too, I also made custom neigborhoods which took the names of them but i removed them when putting Strangetown and Pleasantview back in game.

I have no idea what i have done for this to happen i have never been in these hoods before but today when wanting to play in them they were missing lots and families. If you know what is wrong please reply.

i'd say they are corrupted;download clean ones such as meetmetotheriver's or dread pirates from tumblr.

You haven't necessarily done anything. All the base game lots ship corrupted, and if you never played them, you hardly had any opportunity to break them further. And removing the custom neighborhoods with the same number rather than overwriting them was the correct thing to do.

You should check to make sure that your anti-virus whitelists all your game files (or turn off your anti-virus when playing), as a precaution.

If you install cleaned hoods and this happens again, let us know and we'll figure something out.

If you don't want to use the cleaned hoods, you can always reset your Maxis neighborhoods by renaming your The Sims 2 folder and loading the game. The game will regenerate a new The Sims 2 folder, including all the hoods. Copy the ones you want into your renamed folder, delete the new one, change the name back on the old one, and you've got them.

Did you move out the new ones and move in the old ones, or did you let the folders overwrite? If the folders overwrite, you'll mix old and new files, and the neighborhoods most likely will get corrupted.
