I've created a 28 page document, and when I try to export it as any kind of PDF, everything looks just fine and shipshape on the preview screen... then the PDF opens up and these pages have just been left out of the printing process at random: 2, 4, 6, 10, 14, 18, 20, 22, 24.
When I print it as a booklet PDF, again, the preview screen shows all the pages in the proper order. However, once the PDF comes out, they're all jumbled up in no kind of logical order. E.g. The first spread is a blank page with the cover on the right, the second spread is page 3 followed by the back cover... it just makes no damn sense whatsoever and trying to figure it out is driving me INSANE.
