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 :(

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.

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'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. 

ferdiewiangit definitely is not a mod problem as I have had this bug happen multiple times recently and have never used or downloaded any mods

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 

Same issue. I don't know how to fix it. I aged up my teen and her boyfriend to young adults. She went through the whole process. He aged up but never did the trait option. Now they're both young adults and they won't woohoo at all. Doesn't work. I've edited in CAS to add the trait. I've aged him up and down. Nothing is working. I did not download any new content when this happened. I don't play with mods. I'm on PS4. Hoping they put out a fix to this.
