No, you’re right. It just plays out the scene as if I didn’t have the princess doll. So the hero defeats the dragon and then it says something is missing.
I did try it before when I didn’t have the doll so maybe that’s why? But I’m not 100% sure that’s the reason either. Could be because of the story progression or the page collection progression? I can’t help you much because I don’t actually have a save file from before all this, I just saved over the same slot.
I tried a few other stuff though, like exiting the room and coming back in and trying again. I also tried touching multiple times, but that didn’t help either.
