Neighbourhood disappeared!

[xangelx]

Yesterday I was playing my legacy family in a custom neighbourhood, I saved the game as I normally do and exited.
Today I ran the game and went to select the neighbourhood, but it's completely disappeared off the list.
I checked in my documents and the files for the neighbourhood are still there and look normal.
But I ran simPE and although the neighbourhood appears on the browser it is called 'unknown' and says it was created yesteday at 19:30 :|
Have I lost the neighbourhood completely? Or is there something I can do?

Is there any way that I could copy the character files into another neighbourhood?

It's a good idea to not move your Sims from one neighborhood to another. It will really screw your game up.

No kidding. I decided to move all my Pleasantview (the base game characters) to a new neighborhood "Teirace Lei" and then I installed a new EP - now I have two sets of Pleasantview characters - just living two different lives. Its a pain in the arse, lol.

I wish I could help. If I think of anything, I will come back to this one.
