If your game crashes, please copy and paste the full error message below, or post a screenshot of it.
Please describe in as much detail as possible how to reproduce the bug or crash.
Access the library through the menu, not through the bookshelves in the actual library. (Possibly works that way too. I didn’t test that.) The windows that should be on top is not. See image.
What operating system are you playing the game on? Windows, Mac OS, Android, iOS, or Playstation?
What game version are you playing? You can find the version number on the title screen in the lower left corner.
