We’ve made some changes that will allow Sonarr to get these additional and process them, but they are named in such a way that Sonarr will either fail to parse them properly and assume it’s a full season pack or will only see it as a single episode number (parsing Part1 and Part2 as episode numbers in a mini-series.
We may be able to improve the parsing to handle partial season packs, but that would be for filtering purposes because Sonarr has no concrete way to know whether it should grab it because it doesn’t know which episodes are in each pack.
Not sure if it could be planned for but the way they split them is according to this
"New seasons for anime series that are split cour (where a season contains a 3-month hiatus) can be packed in their individual cours (as organised on aniDB). Long-running, multi-season series (containing 52+ episodes such as Naruto, One Piece etc.) will continue to be packed based on their story arc (as organised on TVDB). What this effectively means is that a series such as GATE that aired for two cours (1, 2) would have had its first cour packed as “Season 1.1” and its second as “Season 1.2”
I also believe that a cour is defined as 13 episodes so there should always be 13 episodes per cour in any anime that has been organized as season 1.1 1.2 ect
What markus is saying is that we can already handle the Season 1.x groups on btn. but the ‘Space.Dandy.S01.Part2.720p.HDTV.DD5.1.x264-denpa’ Is a different thing because it doesn’t follow Anime format and thus isn’t parseable.
