Well this is definitely a bug, usually this happens when the label is empty or there is a "return" in the code. But it shouldn't happen, the only possibilites should be she awakens or you finish the number of action for the night. I think I found where the mistake was, but it's odd that it did that, thanks for telling me, and thank you for enjoying it, I want to bring waaay more for the battles!
Oh and also in the Loading menu check the "A" next to the Q and the numbers, it's the Automatic Save system, maybe you got lucky with it and have something to work with for that save! (If the bug does not persist that is.)
