Ideas
So just realized that one of the above post is right, I think it is tied to HS graduation. One of my sims that was expelled from HS in the same save as my other sims, was able to blow out a bday cake and age up with the option to pick another trait. I haven't tried with a sim that graduated early but maybe it will have the same result? Either way EA please help!! I want my sims to be able to attend HS grad and age up like they're supposed to. Thank you!
Scorpiogirl92 Interesting. My older teen graduated. The whole family attended. The next day aged up the younger teen and no traits to choose or assigned for character. And nothing about their high school graduation (like valedictorian or otherwise). I am wondering though, if there is something having to do with the High School Years where no teen other than the oldest counts. My younger teen never had tasks to do and didn't get any career day participation prompts.
