[HSY] Sim without a crush keeps getting crush related moodlets

This happens with every crush any of my sims gets. I've had sims grow up, get married, and grow old together, and throughout their whole lives they constantly get crush-related wants long after the sentiment is gone.

I've tried having them get over their crush when the option is there, but it always comes back. I've started using the "modifyrelationship" cheat to remove the sentiment which works for a while, but when I return to the house (I play rotationally) the wants are back again.
