Extremely weird bug, 0 folders, hidden accessible library??

[unleashed7]

Something really weird happened, I didn't access my server for 2 weeks so not sure when and how, but my server is half broken.

- All libraries have 0 folders
- No entries in any of them
- 1 library still accessible, even though it does NOT show up in the Libraries menu

How can this be? Where did all my data gone, and if it's gone why can I access perfectly a single library?

Also, why is the library not in the Libraries settings, but still accessible?

Btw, all my metadata seems intact (images, descriptions, watch data), except the libraries itself.

Is it possible to readd a library without a metadata scan? I have hundreds of custom covers I wouldn't want to lose!!
