Cut 6mm out of the rulebook so it fits into the gamegenic box.
I bought it thinking it would fit.
I think there's a chance future campaigns will be the smaller 'Children of Blood' size, even the five scenario ones.
My strategy: flush book with wood piece, place ruler on top, place spacers in between (I used 6mm cylinder magnets), weigh down book, and cut with knife.
I think it turned out pretty well. Still a lot of margin inside.
