I recently was introduced to Dragon and Dungeon magazine and I'm putting together an excel file to help track my growing physical collection. I have noticed something odd and was hoping somebody could clarify this for me. Dungeon #150 was published on September 2007. However, Dungeon #155 wasn't published until June 2008. How is this possible? What months was the magazine not published?
