from jellyfin.

I also have this issue: I noticed that my customized collections kept changing, with movies disappearing and I couldn't find out what the issue was.

It finally just happened in front of my eyes: I was in the Monsterverse Collection, which had 6 or 7 movies, and then right in front of my eyes most of them disappeared, leaving only 2.
The collection was also renamed by Jellyfin Godzilla Collection (its original name).
Within 30 seconds I downloaded the log, which hopefully will shed some light on this mysterious behavior.

Realtime monitoring is not enabled.
Log is below.

Can you check this path actually exists?

Nope, it doesn't exist.

Playlists were affected too.

I think the newly added task for cleaning collections and playlists of not existing items is responsible but I can't see how this would happen without the files being not there - for whatever reason

WEll it is widespread on my end and I haven't deleted anything that I recall. Perhaps moved some stuff, but the amount it has affected would not be for that.

In my case, no files were removed: I just changed the collections.
