Did something similar to foxworks with similar results. I loaded page 1, then moved forward page by page, using the right pointed bracket.
When I loaded page 1: Console printed calls to load pages 2 to 13.
When I moved to page N (N = 2 to 11): Console printed calls to load pages N to 12 (NOT 13).
When I moved to page 12: Page did not display any boxes. Console printed calls to load page 12, then got error:
