I think I've found a bug in the Italian translation. the command [new_page] used in the books/writings in game was translated to [nuova_pagina] making it show up in game and not doing what it should, lucky enough the game splits the page anyway when it finishes the space available but still it looks strange
changing it to [new_page] fixes the problem.
edit: while here during the installation of the linux version at least after the serial is input and you press the button to proceed you get a window with a message which looks like a mix of english and italian.
