When editing a book and quill that is not signed, if you do not select the text properly and try to press Delete, you will crash. I've tested it 3 times and that is 100% the issue. Edit, I have tested the issue further and when reopening a book and clicking on the last character (at the end) trying to backspace then will cause a crash. If it is not the end character it will no delete the correct characters also. When i was deleting instead of deleting a character sometimes a random letter would pop up.
