It did pass 16 chapters. I'm not sure, because I wasn't following its progress, but I'm fairly sure that the author got up to at least Chapter 21 before he disappeared. DB Sommer, over on Anifics, has commented at least once that he was actively writing side stories, and even corresponding with the author regularly, before it stopped without warning. DB isn't sure what happened, but he suspects it was something bad, and he doesn't hold out much hope of the author returning, if I recall correctly.
