Sleepover sims reacts to nude 1 repeatedly

I had a weird bug. I have Get To Work and Get Together.

I had my Sim (Who was already in her Nude 1 outfit) invite a Sim she was lovers with to stay overnight, then had the two of them woohoo. They had had their first kiss just moments beforehand. After that, she went to sleep, but the guy who was staying overnight went to sleep with her just to wake up, gasp at her nudity, then get back in the bed and go back to sleep, just to get up to gasp again. This cycle repeated continuously.

Sims give the gasp reaction to a naked sim every time they "see" them, no matter how long it's been since they've seen them last, is what it seems like.
