[ARCHIVED] Teen to YA aging doesn't always give option to add third trait

Sorry for continuous posting, but I got another teen sim who couldn’t obtain the third trait and traits of Character values.

Please note that:

1. I usually play Japanese version, so proper names such as sims’ names and lots’ names will be shown in its characters.
2. The teen sim is at Affluista Mansion in Oasis Springs, where Landgraab family originally lived.
3. The sim is only teen in the household, who has red hair.
4. He will become older within a few sim hours.
5. He is a vampire, but it’s not genetic - his great-grandmother was a vampire, though. Caleb Vatore turned him into a vampire when he grew up into a teen.
6. I replayed it several times to see if his action, location or club gathering affects the result, but he can’t get any traits whatever he does or wherever he travels as far as I tested.
