Problem picking up changes in nfo files

[ZmgwsYzhM2nV]

Before I'm going to raise this as an issue on GitHub, I want to make sure whether anybody else is seeing this problem, or perhaps I'm doing something wrong. The problem is that changes in nfo files are not being picked up doing a library scan. I don't use metadata downloaders ("scrapers"), I solely use nfo files for metadata, and my own artwork files. This problem started a few versions (of Jellyfin) ago, and I confirmed it doing an install of Jellyfin version 10.10.1 on a fresh install of TrueNAS Dragonfish-24.04.2.5 (using Jellyfin as a custom docker app), and on macOS Sequoia 15.1. I didn't test some Linux variant as of yet.

- When I add a new movie or show, the metadata in the nfo files is picked up properly.

- When I then edit the metadata in the nfo file and do a rescan, the changed data is *not* picked up at all.

I follow all the rules when it comes to directory structure, file naming etc. Here's an example of a show episode's nfo file:

Code:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<episodedetails>
  <plot>Comic chaos ensues when Edmund accidentally kills King Richard III.</plot>
  <lockdata>true</lockdata>
  <dateadded>2015-02-16 08:06:16</dateadded>
  <title>The Foretelling</title>
  <year>1983</year>
  <imdbid>tt0526541</imdbid>
  <showtitle>Blackadder</showtitle>
  <episode>1</episode>
  <season>1</season>
  <aired>1983-06-15</aired>
</episodedetails>

Any suggestions how to troubleshoot? This behavior started something like 4 or 5 versions (of Jellyfin) ago... Maybe I'm the only one using just nfo files for metadata and not metadata downloaders, LOL!

Thanks for any pointers!
