High School Graduation will not trigger!!!

I play on PC. I have 3 teens in my current household. One is aging up to a young adult and has straight A's in school. I aged him up via birthday party, the high school graduation pop up I normally get does not appear. I also get nothing saying whether he is valedictorian or graduating with honors. I restarted and let him age up on his own, still nothing. I restarted again, let him age up and waited a week because I saw some players say it triggers the following sim saturday...well you guessed it. Still nothing. I need this fixed, its ruining my story. I also play with no mods or cc.
