Okay... I've also noticed that one or two of the navigation thumbnails (sorry; not sure of their proper name) at the bottom of the iBook are blank when displayed on the iPad.
Unsure if this is related to my vanishing page(s), but thought that I might as well log it here.
For what it's worth my .opf is below
Any pointers would be much appreciated.
