As you see, there’s a “grab from indexer and sent to download client” and a “download successful and picked up from download client” event but I’m missing an “episode file deleted” event. This means that the original download folder is not deleted and for this particular instance I have this leftover file:
That event only shows up when upgrading files (or when Sonarr detects the sorted episode file is deleted), it has nothing to do with the source folder not being deleted. We’re beating a dead horse here though, since this is the same topic as at least one of your previous threads.
