I've found that with anime that has only a single season (it may be all anime in general; I can't recall, exactly), it doesn't get "S01" in the title. Instead, the entire S00 is skipped and I just end up with Title.E01.Name instead of Title.S01E01.Name.{n}.{s00e00}.{t}
I've checked this with TV shows and they do get renamed with a S01 (etc), but anime does not.
Suggestions? I'm really tired of manually adding the S## to 12 - 26 files >_>
