Starting this week, sonarr is importing episodes as the prior week’s episode.
i.e., S01E04 gets renamed and imported as S01E03.
S01E03 gets renamed and imported as S01E02, etc.
…and S01E04 gets renamed and imported as S00E09.
Nothing unseemly in the logs.
You can test this by adding the series and putting a fake file in the drone folder.
EDIT: Never mind. I see that’s just how “they” do it. Apparently thexem was updated recently to reflect the new numbering.
