Solved
Can't enroll in university or travel...
It says "The adults are already travelling" when they aren't.
I haven't sent any of them to vacation I think, it was only recently when my sim came back from uni and I think the grandparents went on vacation I can't remember. There is no picture in their emotions panel saying they were on vacation.
What should I do?
Reset:
- open cheat console (shift, ctrl, c)
- type in: resetSim *
- hit enter
Try again, if that doesn't work, try this:
- go to edit town (can be found in the popup menu along with save / quit / options )
- click on household and move them out (split household works quite nicely)
- put them back in and take them as your active household
I would also save the family to library before evicting them
