The only other thing I could think of is… do you know if you activate a levioso or confringo field page object, but possibly forget to collect the page and leave the area, what happens?

Do the books only appear at certain times of day? And I know the gargoyle is not there… but I got the collectors edition achievement so if worse come to worse this last piece can wait. Thank you, though.

Hey mate. Sorry for the late reply. If I'm to take a guess it's likely one of the annoying floating books. There's a really hard-to-see one in the Bell Tower Courtyard museum area. There's also another one that does a lap around the beast class too, You may have also missed the book flying at the top of the Owl Tower, or potentially the gargoyle along the northwest wall in the grounds.
