Billy Idol's page

Hello. I recently received my copy of in Hell's Bright Shadow and several pages had two pages printed on a single page. i.e. Page 24 had page 2 printed over it as well. This has affected a total of 9 pages in the book. How do I go about getting a replacement copy?

Does anyone know if Paizo has published a poster sized map of Absalom? I remember a smaller one in First steps but have yet to see a poster sized one. A poster sized map would be very helpful when running games that are set there.

I'm interested in making a Witch with the Magaambyan Arcanist prestige class from Paths of Prestige. One of the requirements for taking the prestige class is the Spell Mastery feat which has a prerequisite of 1st level wizard. Therefore according to the current rules in place my witch would need to take a one level dip into wizard to qualify for the prestige class, however upon reading the class features it specifically mentions the witch and the usage of the witch's familiar, leading me to believe the original intention of the prestige class was to make it open to more then just wizards. Is there going to be any clarification or errata concerning this in the future?
