You can now duplicate/back-up fully written books (Since it's an ass if you forget stuff in a book you lost. Also, it doesn't have to be 9 - it can be however many duplicates you want.):

Fishing will now give multiple outcomes. There is a list of "bad" items and a list of "good" items. Examples given: Lilypads are part of the good list, while damaged leather boots is part of the bad list.
