This side-loaded book makes my Kobo Forma crash as soon as I get to the end of the index at the beginning and try to go to the next page. Jumping directly to the first chapter using the TOC works, but the book crashes a few pages later anyway.
The non-scrambled book is only 2.3MB and epubcheck couldn't find faults with it; this crashes the Kobo both in EPUB and KEPUB formats.
Does anyone have any tips?
