When I upload my Sigil-produced EPUB file to KDP and it processes it to make a MOBI file, the MOBI file works (I can read it and navigate it using GoTo commands), but it opens (in the Kindle Previewer) halfway through the TOC.

If this was a problem with KDP's converter, the answer to my problem would be 'Ask THEM why it happens', but their answer would be 'You should have used OUR tool to get from HTML'.

But I doubt if it IS their problem (at least, not a problem with their converter from EPUB to MOBI), because when I try to open the EPUB file directly (as it's a supported input format for the KDP Previewer) it fails almost immediately with the error 'Kindle Previewer has failed to compile the book'.

Any ideas?
