u/tatere

Every so often an episode or two in a series gets skipped by the usual release group. Then weeks or months later, the missing episodes are listed as having releases (in srrdb for instance). But I can never find those "new" releases with my normal set of nzb indexers. Is there somewhere else I might look? Might the releases be in the relevant usenet group and just never got an nzb put together because it's outdated? I am not super clear on the real structures involved so forgive me if I am putting this badly.
