Relationship bug

Hello,

I’m contacting you regarding a persistent bug related to the relationship system in The Sims.

Relationship bars behave abnormally: after only 2–3 positive or neutral social interactions (chatting, compliments, friendly jokes), the relationship suddenly drops or turns negative, without any negative interaction being triggered.

This happens even when:

Sims have compatible traits

there are no active fears or negative moods

autonomy is either enabled or disabled

only positive social interactions are used

The issue affects friendly, family, and romantic relationships and prevents normal relationship progression. The problem is consistent and reproducible.

Notes:

playing with no mods or custom content

Sims have been reset

cache cleared / game repair already attempted

the issue persists in my main save file

This save is very important to me, as I’m currently on the 4th generation of my family. Not being able to play properly is extremely discouraging.

Thank you for your help.
