SOLVED: Jellyfin removes new content after every scan

[TheDreadPirate]

I think this is expected behavior. Expected meaning that Jellyfin is coded to behave this way. I think Jellyfin uses one of the file creation/modify dates. In my experience, renaming files shouldn't trigger this. But re-encoding probably would since it appears as an entirely new file as far as jellyfin is concerned. I've always waited until I re-encoded files before I added them to my library.
