Weird dancing glitch!

Hey everybody! Today while playing, a really weird glitch happened where one of my Sims was stuck dancing no matter what she was doing. Here are some videos to help explain:



Sorry for the bad quality of the videos, I didn't notice how low quality I was making them until after. Anyways, this glitch is hilarious, expecially when swimming. It didn't happen with any of my other Sims, only this one.
