And that's the annoying part: it was way harder to corrupt a neighborhood before.
Before, reports like that were really rare. If you really wanted to see $Subject, you'd had to delete character files manually from the File Explorer. Other than that, it was mostly caused by removing custom clothing, careers, majors, foods, NPCs etc.
Yeah, this is unacceptable. We should report as much as we can, as this is a really great game and it's a tragedy when it's overshadowed by bugs.
For now, my only recommendation is to not play it seriously: try different playstyles, life states, gameplay objects etc. The more we can report, the better. I do hope that one day this edition gets fixed enough that people can play it.
Edit. Oh, and people report that both of these games run better on Steam than on EA App... Ugh...
