Sims 3 unknown, really odd sound glitch
I have a horribly annoying glitch in my game I just can't seem to get rid of at all. Today I was playing with my sim and she just finished drinking a juice. Then she started to walk towards the trash compactor to clean it up when I gave her a new command to do after finishing with her task. However something went wrong and now the trash compactor's sound is attached to her! I tried many things, make a new save, exit, return, moving her out then in again, buying a new compactor, verifying game cache, even deleting package files, using resetsim but to no avail... worst of all, it got to the point that it started to effect all of my sims in other saves. For last resort, I moved the entire Sims 3 folder from my Documents folder to another drive - the newly generated content have the same problem. I'm out of ideas and this makes the game unplayable.
I also tried looking for solutions everywhere but it seems like no one else have this exact same glitch. I'm really desperate for a fix.
(I play the Sims 3 via Steam and have the base game, Pets, Seasons and Generations if that counts.)
