Teen keeps leaving school early (bug?)

[Wistala]

My teen keeps leaving school early, at about 9:45 each day. It doesn't effect her performance, I get the same message as if she'd come home at the normal time. It's only the teenager, her sister who's a child isn't effected.

Edit: Another weird thing happened, the child just aged up to a teenager. She had an "A" in elementary school but when she aged up she became a grade F high school student.

Sounds like it may be a mods issue? Do you use mods in your game?

I have the MC command mod for a fallout vault playthrough I'm doing. I don't use it for my main game, but it is installed.

Try removing it temporarily and deleting the localthumbcache.package file and seeing if that sorts the issue out.

I have this issue, too. I've never downloaded any mods - at least, none of which I am aware. I'm usually good at making sure anything from the gallery is non-CC.
