I've seen this bug mentioned a couple times here before, but I never found an answer.
Whenever I try and deliver a package to either Mio or Vivi, they halt all progress and begin staring at me without any dialogue. Hana and Juno packages work fine, but Mio and Vivi seem to break. The only way to leave the bug is to either load a previous save state or close the game.
I have been trying to avoid making a whole new save because I have all the girls' schedules filled out and I don't really want to do that again...
