Chat Does not work anymore, You or another play can say something in chat and it'll never show up for either player But yourself.
When writing on Signs Nothing will show up or save onto the sign if that makes sense.
When writing on an already written on page in a book and quill It'll Remove/Delete everything that was written on that page when re-opening the book, Same with writing on a Blank Page.
