The Vault 108 location of Tumblers Today is clearly a bug. The only way to access this book is by wedging an explosive under the stepladder to move it. This is an extremely trial-and-error prone process, as the collision box for the stepladder will prevent you from interacting with it in any way, including the 'move' button, despite being clearly visible and close enough for taking.
