That 9th demiguise is frustrating, it's the one upstairs in the three broomsticks and it will not spawn. With any luck it will eventually if I keep going back. Great guide
I'm working on it. The South Wing (100% Collectible Guide) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4cwWqu8hDZE.html The next one is (30 mins) The Astronomy Wing (100% Collectible Guide) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NVusgJZx-VE.html
For me they were two flying pages right over The Magic Neep and the hill right next to it (northwest) and stupidly enough, the only revelio I was missing was the Hogsmeade one (where the main bridge starts outside the village)
The flying pages and the moth pages don't really have any way to designate them. It's frustrating, but until a comprehensive list is made, a guide like this is the closest thing you'll get. The revelio pages are the easy part. They have entries in your guide
