I know, I know, something else...

Ever since I got supernatural I had this one specific child-aged sim (created in create-a-family as part of the family I planned on playing a new game with) whose voice set would change on its own. Using MC I would edit the sim in CAS and return the voice set to what I had chosen on creation... only to have it change back to what I did not want it to be anywhere from immediately after exiting CAS to a sim day later.

Outside circumstances caused me to completely uninstall and reinstall the game where I recreated the same family and the same child-aged sim had the random voice set changing problem.

It would revert to the voice set I had chosen at creation when it would age up into a teen and I would not have any problems.

However:

This time around I currently have a family that has 3 plumbots, 3 teens and a child (I killed off the YA parents because their stupidity horked me off that badly). I decided to take this family on a vacation to a different town (not a WA location so it the town load-up was similar to entering University Town).

By the end of the first day there, all three of the teens had their voice set change. I changed it back in CAS, one of the teens had their voice set change again shortly there after... but then the game crashed.

I am wondering if this is due to inherited voices, especially without the parents (even though I am fairly certain the family tree is still in tact). It is the only thing that I can think of, but I honestly have no clue what is causing it or how to keep the voice set from changing on its own...

Any suggestions on if I missed a setting or I'm just excessively loved by Murphy's Law... yeah...
