In the part where you go to the closet and inspect the books it gets glitched to where i cant return the book and cant inspect the other ones.
Just had the same issue. Yeah, the big purple box that says "inspect book" from the "stuff" book stays on the screen after you put the book away, and you can't pull out the box anymore. You can still pull out the first 3 books from the side of the screen, but the "stuff" book is still the one that opens up again.
