In my experience, cheats are something you use at your own risk, they can impact game play in unexpected ways. I've been playing the scientist career and haven't had this issue. Then again, my sim isn't particularly special. She worked her way up from the bottom. No college. She didn't finish her first aspiration until after she reached the top of the Scientist career. Also, I don't own all of the packs. I can't rule out the possibility that this is a glitch caused by an interaction with something in a different pack I don't own.
