I’ve been experiencing at least a variation of this problem which started when they moved over to the new modern plex agent/scanner. I outlined in this thread Plex Episodes changing from played to unplayed due to online metadata source change (anon5074910 is my previous forum username) which unforunately like a lot of things around here got ignored.
Basically what I think maybe happening for you is …
- Years ago you add a show, match it, watch it and all is good
- Then years later you rip the show again and want to replace it however the show has had the episode order change from one of the online metadata sources (this happens more than you would think over at tmdb, especially for older shows)
- Now when you migrate the media to its new directory / location plex re-matches is, refreshes the metadata and as its now new the internal plex guid for the episode has changed and boom your watch status is gone …
Would you have an actual example of a show which this happened for you, I’d like to see what changes may have happened over the years for that show.
