In Sonarr I have ‘Completed Download Handling’ set to Enable=Yes and Remove=NO.
Once a download has completed in uTorrent, Sonarr then copies this file to another location (as per my setup), But it also physically removes (deletes) the file from the uTorrent download directory even though I have ‘Remove=NO’.
It does not remove the entry in uTorrent though. This has only started happening around a few weeks ago…sometime in Jan I believe.
