My teen twins are celebrating their young adult birthday, the first YA birthdays since the toddler patch.
I was quite surprised to see this menu after the birthday leap. As you know, a young adult sim usually has the option to choose a third trait.
I don't mind this type of hiccup at all, since it doesn't adversely affect my game.
Just wondering if it's related to pre-coding of some form.
Edited to add: The same thing happened with the twin, who initially had the Chief of Mischief aspiration.
Upon choosing Renaissance Sim at the birthday menu, I see he has both the Dastardly and Quick Learner traits.
I like this addition very much and hope it's not a bug.
