I donīt know if i found a bug or missed a book, but after searching though all the house (both real and dream version) i couldnīt find the Nourishing Rage Book, and yet i found one copy of all the others and 2 of the Joyless Triumph.

Considering i didnīt found 2 copies of any other book, this is my question?

There are 2 (or more) copies of every book and i need to up my party perception or there should be only one copy of each, and i found a weird bug that made impossible to complete the puzzle?
