If you unpublish a book and then update the unpublished first book page the hierarchy of the very first book in the system will mess up:
- The unpublished book and the subpages become members of the very first book (though you won't see this page and the subpages in the book hierarchy on /admin/content/book/... <7li>
- if you remove the former book from the very first book, all subpages become direct subpages of the very first book. You have to manually remove these pages from that book
This is not a duplicate of #26552: Allow users with administer nodes perm. to create unpublished books. or #353125: Unpublishing book parent breaks book hierarchy because this is a really annoying bug!
