Last week I published a new version of a book that has been up a couple of years. In the past, it always opened in the middle of the TOC, as many of my books have done. This time, without any change in the Sigil semantics, it opened at the title page.
I quick went back to the Sigil epub and inspected it. Sure enough, I had labeled the title page as Text, and it showed properly in the Guide section. (Which I hadn't changed at all from the original version.)

It doesn't explain why neither KindleUnpack nor calibre can extract either a working html toc or a working ncx from a kindlebook whose Go To sections clearly functions properly (the entire toc is available--and works in Kindle for PC. After extraction, one or the other (ncx, or html toc) should be valid/working.
I'm not ruling out something wrong with the Kindlebook, but the simple fact is that if the toc works in the Kindlebook ... then KU/calibre should be able to extract a working version of it.
Either something has changed on the Kindlegen end, or this book contains something that KU/calibre has never encountered before (or both).
