Description of Bug:  Writing a title in a fresh book consumed writing time (and likely ink) but didn't save a title. I tried twice while the book was blank, and once after it had writing on one page.
Reproduction Steps: 

1.  Have a blank or player-written book with no title
2.  Write a title
3. Wait for your character to finish writing
4.  The book's position in your inventory is refreshed to the end as though it has been edited, but retains the title 'Book' with no text on the cover page
