In one hint there is build option then for cat and aurora it says get the pajama I have all the requirements to level up but can't get the pajama option for cat and aurora
Maybe it's a weird bug. Once you've completed the rest of the events with the girls those options should appear immediately. Please try starting a new game
No need to restart, i had same problem, hints are too vague and event sometimes not starting according to it. But this thing started after chef sister saw new room.
