Sims won’t stay in bed if music is playing in the same room

That’s baffling to me. I only started playing Sims with Sims 4 and I’ve been playing for 2 years now. My sims (and my daughter’s sims in her game) have always been able to sleep with music on in the bedroom. I couldn’t begin to guess how many times I’ve had the romantic music playing in the bedroom while two Sims woohoo’d in bed and then slept through the night afterward with the music continuing to play. Same for my daughter. Now, though, I think since the the update and patches in June, the Sims won’t stay in bed when the music is playing. That’s bizarre to me if you are telling me that they were never supposed to be able to sleep with the music playing, because for both of us, they always have.
