i have noticed that the fake rest points have a very obvious way to tell from the real one, the fake ones' text doesn't disappear and the text stays there with the option, while for the real one it only shows the options and the text disappears, is that a bug?
edit: it's the same with the mimics too
Never noticed it before (and I've been playing this game for a long while!), but you're right, the text stays put if it's an encounter with Shizu or the mimics. I'm not sure if it's a bug or not, part of me feels that it's there to let the player know "this is an encounter" in case you need to prep first.
