The Sims 3 Glitches

Damn Guitar crushing my dreams...
This has happened to a few of my sims that picked to become a rockstar.
So to get more promotions in the music branch you have to practice the guitar a lot but i notice that at some point the guitar gets stuck your god damn chest! EA didn't do a buggy check they did a "Lets make are fans wait longer because we're evil bawahaha! donuts for all!!"
