Is anyone else having this problem? I think it happened after the last update. I thought it was just my game so I reinstalled everything and started fresh but I still had the same problem. The opportunity shows up but there is never an option to go and eventually the time passes and they miss it.
I've done a little bit of testing between the Moonlight Falls style of school and the base game type of school.
The base game-type school lets the kids attend the badging ceremony and recital, you can just click on the school building itself and select the hi-lighted option of the opportunity.
But on school building types that are combined with another rabbit hole, like the stadium or something, that's when they can't attend those things.
When you click on that particular model of building, it will only come up with the School and Stadium tags and of course if you click on the school tag, it won't have the option to attend the ceremony or recital.
The only thing that shows up is " Go to School" which of course is greyed out by then.
Or "Quit Afterschool Activity"
So it seems to be some kind of problem with the dual-rabbit hole school model.
I also had this problem, in the Moonlight Falls combined school building. I can't think of any workaround, which is sad because my sim is at level 3 and i want him to get a cool trophy. Maybe i'll have to replace the building with a regular school and see if it works then...
