Teenager don't get third trait on aging/no Graduation

I am currently experiencing the same issue and can't seem to find a fix. I've tried disabling mods, restarting the game, using the repair function, etc. Teen sim is still aging up without prompt for a third trait and no character values. I think it is an unfortunate bug with the latest update. Hopefully a solution comes out soon :(

Today I had an infant age up to toddler, child, teen, to young adult all at the same time! I dont play with mods my gameplay is base game vanilla. 

I wanted to make sure it was reported and saw this thread.

Same here. It just has happened to my game since few days ago. 

I am currently having the same issue on Xbox, my played household seems to age up just fine but when I go to age up my sims partners they don’t get the prompt to choose their third trait, it also breaks the ability to woohoo/try for baby as well. This is honestly so frustrating as nothing I’ve done has fixed the issue 

Update: the above also happened with non-adopted teens. They aged up without prompting for an additional trait, and no gained traits from childhood they should have had (eg. Happy toddler etc). Additionally and separately, one of my sims aged up autonomously, and aged up again immediately afterwards and likely would have died if I didn’t intervene by going into cas.

I'm having the same issue. I tried it again, but same outcome. It seems to be a feature now. Not a bug I guess. Probably will be fixed with a big update. I hope they fix it sooner. Family gameplay is what made the sims and now it is broken.

I went back enabling the mods and it’s been resolved. I normally play with mods but I did it once, so maybe that’s why this bug occurred.
