Since the FAQ says
Q: There is a missing chapter here at StopTazmo
A: We sometimes miss chapters it does happen, this is not really a download problem, but post anyways letting us know so we get it fixed, it's hard to update about 100 manga series and we sometimes miss a chapter or two.
I'm going to post a thread about this : the file for Fantasista 10 has the 11th chapter, so the 10th is actually missing from the site.
