Ideas
I started having this bug just after I bought the Life and Death pack last week. I only have one household I play on this save that has teens at the moment and there’s 3. I do get the pop-up that asks if I want to join my sims or send them alone. And two of them don’t have the tasks and at the end of the school day it shows they are still at school with no house button to click on their profile icon at the bottom. Only way I send them home is by traveling using the phone or map, or clicking on them and have them each go home. But if I send those two home and the third one that does get the tasks, it shows an exclamation mark for the other two and hovering over them says they are at school even though I sent them home. I haven’t tried my other saves yet.
