Sims forget already existing relationships

I am having the same issue - even with smaller save files. Sims keep having to reintroduce themselves to other sims they have met before. No mods but CC. This is happening in all of my save files. 

Ever since the update I have had Sims that I know my Sim knows randomly just vanishing from their list of people they know. Sometimes they are just acquaintances, sometimes they are even friends. They just vanish with no reason or explanation. If I go to the household of the Sim that vanished, they know longer know that Sim either.

It's really wrecking immersive gameplay and storytelling. 

my sims cannot make friends with other sims cause the whole progress gets deleted. its only about sims from outside the family. inside the family relationship progress saves just fine

My Sims keep forgetting relationships. They forget even when friends. It seems to be worse with the household that is being played most. It's getting annoying having to introduce self again multiple times every play session.

I'm having this issue now. Sims forget relationships even when friends or higher. 

Hi, recently playing enchanted by nature in Innisgreen world with multiple households. my sims made friends with each other from different households and after loading screens, the connections are lost - go back to strangers.

No CC/Mods. Repaired. EA APP on Macbook.

I'm a PS5 player and I'm experiencing the exact same issue. It's happening to some of my Sims, not all of them. Even when we become good friends, the next time we meet we have to start introducing ourselves, which is sad.

i make friends with sims outside the household and it deletes completely every time i load the game again. yes i am saving it every time. also after my sims's husband died she didnt have any relationship with his ghost anymore.

There needs to be an option to turn off relationship culling. This also happens to every single family in my entire sim save when I enter a home through build mode instead of live mode. 

Please EA make this a top priority when you spend 8 weeks working on issues - this is not an esthetic issue, this is a world-building, gameplay issue that is making anytime spent in the Sims useless.
