Is there a way to undo changes made by "neighborhood stories?"

You can move your Sim to a new save. 

1. Go into CAS and save him to your library. 
2. If you have modified his house, go into build buy and save it to your library. You can skip this step if you don’t care.
3. Create a small room in the yard, put the contents of his inventory into it, and save it to your library. Ditto for household inventory, if it has stuff you care about.
4. Start a new save. 
5. Confirm Neighborhood Stories is off.
6. Place your Sim in the house you want him in, replacing it with the version in your library if you did that step.
7. Place the room somewhere on the property and take all his inventory out of it, then delete the room.

I’vr had to do this for a corrupted save file myself, so I can confirm it works! He’ll still have his job, his skills, etc. What he won’t have is relationships with people outside his household, so if that’s important, move them in with him first, I suppose, and move them back out again after.

You’ll also lose things like custom holidays and clubs.

 Good luck!
