I’ve got a very odd issue where my library (which is on my server and mounted via AutoFS) occasionally has items that disappear from the interface. There is still the correct Unwatched count on the poster or thumbnail but clicking into the TV source there will be no files (or sometimes only a single missing season.)
The weird part is that sometimes (but not always) the files will then return during a regular update, but the unwatched count will increase like they are completely new files that are being added. If I remove the source and then do an update, it will re-add the missing files and correctly update the unwatched count.
I’ve verified that it doesn’t appear that files are being deleted or modified by any external tool.
Example: In the below log there was originally only (2) files displayed from Search Party. Both were from Season 4 and Season 5 was missing. Unwatched count indicated 12. I watched one episode, unwatched count dropped to 11 but Season 5 was still missing. A few hours later, Season 5’s (10) episodes appeared again but Unwatched count increased to 21.
