[FIXED BUG] Romantic interactions being interrupted in The Sims 4 (Vanilla)

Hi everyone,

I wanted to share a fix I found after struggling with a weird bug in The Sims 4.

Some of my couples (both with NPCs and playable Sims) were experiencing a glitch where romantic interactions like kissing, woohoo, flirting, etc. would start but get interrupted before finishing, with no clear reason.

I tried everything — resetting the Sims, moving them out, adjusting needs, removing moodlets… nothing worked.

But here’s what actually fixed it:

> Make the couple break up, then get them back together.

That seems easy and annoying, but after that, all romantic interactions worked normally again.
I play completely vanilla (no mods or custom content).

Hope this helps someone out there facing the same issue!
