Hello,
A few days back, as this Akuma no Riddle -dôjinshi in the title ( http://vatoto.com/comic/_/comics/akuma-no-riddle-koakuma-no-riddle-doujinshi-r14323/) updated, the new chapter showed up as a "non-page", and still does. Instead of the page, only the usual Batoto background shows. No page numbers appear in the page selection widget, either.
Here's a direct link to the missing chapter:

Thank you in advance!
