I am not sure if this is a Sonarr issue or not. I see some files that were downloaded recently, but have a modified date 10 years ago. How can that be?
File 1: Created = 3/19/21; Modified = 11/22/2010
(Series Original release: November, 2019)
File 2: Created = 3/19/21; Modified = 3/01/2002
(First episode date: November, 2019)
Both files were downloaded using Sabnzbd.
This becomes an issue in Kodi when sorting by last added date (it uses the last modified date)
Sonarr version (exact version): 126.96.36.19944
OS: WIN7 (x64)
