I see it in my US copies as well. The thing is, I didn't alter the Illustrator files from the PDF version to the print version, so something clearly happened when the files were processed. What is particularly odd is that some of the knock-out white type for the water bodies printed fine, while at least one is almost invisible. And some of the yellow type shows over one color while not others...? Some weird printing problem?
I am attaching a PDF of those map pages for those who only bought print copies, and we'll investigate further. I do apologize for that, and understand that it is annoying.
As for the paper, yes that is part of the 'standard' color PoD option. I think we will stay away from page bleeds on standard color from now on.
