Singing Music overlays and never stops

Update

This bug was fixed in Patch 1.36.99.

Problem

• I can hear two different music singing overlays while my Sim is practicing singing or singing Karaoke
• After they stopped singing, I can still hear the singing music.

Cause

Unclear but it seems this issue is occurring mostly if you speed up your game while (or shortly before) you have your Sim sing.

Solution

1. Save your game under a new name
2. Restart your game (completely, not just main menu)

How to prevent

Don’t speed up your game while singing
