Hello!
I haven't found any solution when looking online, so I'm posting here.
I've run into a problem with the Beaker family in Strangetown. Whenever I try to load their household, my game crashes. It's the only household that crashes upon loading, the others work fine.
I've launched the game with no CC, and cache files deleted. I've even reverted the entire Strangetown back to the state when you first load it. Hovewer it didn't help, as the household keeps crashing.

Playing Ultimate Collection on Win 10.
The error message simply says "The application has crashed. The application will now terminate."

Have you tried this fixed Strangetown. The vanilla one had a lot of issues. http://modthesims.info/t/610026

@Sunrader
The family crashes even in the fixed Strangetown.

First right click on the Neighborhood folder and change it to both read and write for all folders and files inside.

Delete the "NeighborhoodManager" in the hoods folder and try a new copy of the hood.

Looks like it works fine now, thank you!
