I am running the latest version of Plex Server on a MAC mini with all of my files on a Synology NAS. I have set Plex to do overnight tasks and have all the boxes on scheduled tasks ticked. Every two - three days, Plex starts to delete all of my TV Shows from my library but the files are still in place. If I stop and start Plex or reboot the MAC mini and do a manual scan it rebuilds the library from scratch, so all of the TV shows are now brand new and I lose all my on deck TV shows and all TV Shows become unwatched again. If I use an old backup of the library (it backs up the database every 3 days) I can get back to where I was three days ago.
It doesn't seem to do this with Movies.
Anyone got any ideas why this is happening.
