Update removed all books in my saved file

Hi there,

I got today's update, and I made sure not to have the mods in the folder while it updated. When I went to look for my Bark magazine and werewolf book in my inventory, I saw that they're no longer there. I then went to the bookcase, and there were no books at all. I went to the library in the werewolf world, and again, the same thing. All the books are gone. 

How do I get them back?

Thank you,
Anita
