My safe file autonomously changes neighbourhood stories setting

Hi, I have a huge problem and I'm getting really mad. I'm working on my safe file. I already had to redo it three times, all lots, households, relationships, skills, careers, etc. and why? Because my game autonomously changes settings for neighbourhood stories. I had specifically on only to adopt pets and have children. But the game turned on everything except of adopting horses. So while I was setting up one of the pre-made families, all almost houses in all worlds got filled up with random sims, which completely changed roles for NPC, like pub owner on grocery stall owner H-on-B, mixologist in Moonwood Mills, those expert magicians like L. Faba, H-on-B has completely random mayor and so on. And I'm really getting so annoyed that I would rather not play than fix yet another * up that's not my fault. And just before you ask - I had no CC since ever and I was careful to not edit/play/move any families that should have these roles, like the ones for Hanford-on-Bangely. Anyone else has this problem? Any solutions? Is there any way I can assign the roles to its previous sims again?
