Yes - there were 2 versions of the book posted. I think it was an error, or they remapped the book. The first download was only up for a little while (an hour or less, I think), and was taken down. If you downloaded the book within minutes of its initial release then you got the version that was subsequently pulled. I know someone else that this happened to. The new book has more interior page detail as well as separate front and back cover maps.
