Check your catalogs! I discovered that I have several catalogs missing pages 13-36. The ones missing pages were just random within the packages. I would have ten okay, one bad, five okay, one bad, etc. In total, I found about a dozen within my order of 100 catalogs were bad. I contacted my local group, and today someone else confirmed they found a catalog with missing pages too. The only way to be sure is to check each catalog individually.
