I'll go to edit stuff in my story flow, and, quite frequently, when I click on a button to select a costume or designate an encounter to beat, it crashes. Reopening the program, deleting my character and creating a new one to test with does nothing, it still crashes every time.

The only workaround I've been able to come up with is deleting whole chunks of the story tree and starting from scratch with that area, but this only works sometimes. Otherwise I'm basically stuck with an incomplete or half-broke objective.
