Now playing through the newest update - during the Nation of Idols arc, when I was supposed to have one girl supporting us staying in the show, it showed a blank white box on the screen and no name in the dialogue box. Later, Fujimoto came to my office and referenced the girl who quit, but he used the wrong name and referred to a girl who's still in the group.
The rival's route is really bugged, too - I've had to use the f7 debugger thing a few times because the next part of the story wouldn't trigger after I completed the task.
