not sure where bugs belong, but Ill just send it here, if you skip the intro you can't talk to elsa/sasha starting from a certain point in the story, think it happens just after you talk to the instructor to "discipline" Sasha
Once you're done training with Sasha in the morning and if you talked to Elsa more than two times in the morning, you indeed can't talk to them. Sasha's sleeping and Elsa simply hasn't got anything to say you now.
