Game crashes when going back with a book & quill

When in a book and quill, trying to go back a page results in the game crashing and saying something like "The game crashed whilst rendering screen
Error: java.lang.StringIndexOutOfBoundsException: String index out of range: 12" on the launcher. For some reason, I cannot upload a video but to recreate this, get a book & quill, write on like 6 pages, then try to go back a page.
