Mischief issues remain

I hate the mischief trait.  Before you started allowing us to use cheats to set it back to 0, I would delete my Sim because I dislike it so much.  Now, even when I have them set to dislike mischief, EVERY SINGLE ONE of my Sims learn the mischief skill multiple times.  As I am playing right now, I have had to reset three different Sims in the span of a half an hour.  This means I have to go to manage worlds, let the game reset and come back to where I was.  It is soooooooooooooo annoying and quite disruptive to game play.  It looks like the developers must LOVE MISCHIEF, but I do NOT.  Pleeeeaaaase fix the game so this does not occur every single time I play.  Thanks.
