{BUG} The Sims 3 Showtime | Stage Performance Freezing!!!

Before my Sim begins his/her gig, they either check their mics then freeze or they just stand there frozen even after the show ends. Other Sims are still standing there cheering on to the empty stage.

Any fixes to this bug? What should I do? It's really frustrating.

This happened last night to me! I tried resetSim. It worked, but I'm not sure how to stop that problem forever.

If you don't know the resetSim cheat: here's an example.

resetSim (first name) (last name)

example: resetSim Harry Potter

I know the resetsim cheat and many others, but this doesn't stop the bug at all. It's VERY STUPID and I paid for my Katy Perry collector's edition for 59.99USD and it's now being heavily discounted. Very VERY unsatisfied at the moment.
