@OwlKseniaThank you! This happened to me on console. I found your post and I was trying to do it on a Sunday. It worked fine on Monday!
Sims team - the problem seems to be for me throwing a birthday party for a teen on a Sunday stopped them getting their parenthood traits (manners etc), their third trait and they also didn’t finish school properly, school just disappeared but there was no notification. No milestone for school. It’s like they became an adult but didn’t ‘complete’ teen.
There wasn’t a problem just blowing out the candles at the sims house with no party, it’s the party itself that is the problem. Like with the toddler trait bug, a new player might not know to look and just think this is normal.
I was on console so no cc or save. I have all packs except some kit.
I had the same problem tonight on Mac - but both with and without a birthday party (just aging up with a birthday cake.) The one with the cake was for sure on Sunday - I didn't save and will try again on a different day, and I can't remember which day the birthday party was. I think it was Sunday though. Sigh...
