Please describe your bug

After adding my existing series and performing a library scan, Jellyfin deleted all seasons of the series. Since these are anime, I thought I was affected by a current bug #11954. However, that wasn't the problem, as the behavior still occurs even after updating to version 10.9.5. My current solution is to mnt my NAS with read only.

Reproduction Steps

Add One Piece season 14 episode 1
rescan library
folder gone

Jellyfin Version

10.9.0

Check your version again, are you running on 10.9.5?

I checked all the possible code paths leading to this log message and I can't see how this could have been triggered on 10.9.5 without someone manually calling the DeleteItem API endpoint. E.g. going to the series -> three dot menu -> delete item on the WebUI

Thanks for quick reply.
I have checked everything again and shut down all LXCs that work with the Jellyfin API.

Same behaviour

I am testing this by manually placing the data in the mounted directory and then initiating a library scan through the web UI.

Are you by any chance using the tvdb plugin?

I have now removed the stable plugin repository and deleted TVDB plugin. Now my series with episodes remain intact/not deleted and the messages in the log are gone. Thank you very much.

When will this fix be implemented and released in the stable version of Jellyfin TheTVDB Plugin?

When I deinstall the tvdbb plugin and restart jellyfin it looks like the following:

If I now restart jellyfin again it looks like this:

Without removing the stable default repository it is not possible to deinstall the tvdb plugin.

Im wondering that a metadata plugin can delete files and reinstall completely automatically. Is this wanted?

Inside system.xml in your config folder should be the stanza <RemoveOldPlugins> set this to true, restart, uninstall the plugin again and restart again. Any future plugin update will now remove old versions.
You can always remove old versions manually by deleting the respective directories in the plugins folder

That worked, thank you very much. However, one question remains:

Im wondering that a metadata plugin can delete files completely automatically. Is this wanted/necessary?

Plugins can do more or less anything the server can, so it is intended behaviour that they can do it but it's up to the plugin to use it properly/at all.
