This has happened a few times now with different books.

Today's case, I edited the text-indents and created a toc. (Manually, not auto-generated.) When I converted to AZW3, the new file had the old text-indents and the toc was gone.

When I tried EPUB --> MOBI, the text-indents were fine, but the toc was gone again.

Re-importing the edited EPUB fixed it - I could convert it, and the text-indents and toc came through perfectly. But does anyone know why this happens and how to prevent it? It only happens very occasionally, but it's come up more than once, and if there's some simple preventative I'd like to set that up.
