Media files get deleted from drive on library scan

[Mattatjahu]

Can you provide your full jellyfin logs via pastebin?  And provide examples of the folder structure, folder names, and file names?  Which metadata source you're using?

Thank you for the immediate response. Apparently it is now sorted out and works without issues. The only thing I did differently this time was to not scan the whole library but rather only update the show itself.
