After upgrading Audiobookshelf to the newest version, it removed all my libraries

Describe the bug

After upgrading Audiobookshelf to the newest version, it removed all my libraries, I had to restore from backup

Context

• Hardware: VPS bought online
• YunoHost version: 12.0.4.1 (testing)
• I have access to my server: Through SSH | through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: 2.13.4~ynh1
• If upgrading, current package version: can be found in the admin, or with yunohost app info $app_id
  Previous one, I update everyday if needed

Steps to reproduce

I did upgrade the app through webadmin, tried command line as well, same result.
I upgraded to the lates version, upgrade performed succesfully, but removed all of the content - my two libraries, which files were located at `/var/www/audiobookshelf/.

Expected behavior

I expected to continue to use the app with the stuff I uploaded...

Logs

No error log since the upgrade was succesfull, here's the upgrade log:

Hmmm, indeed, such data is not supposed to be in the /var/www/audiobookshelf directory, but rather in /home/yunohost.app/audiobookshelf or in an external directory.
Could you move your library to an appropriate place an try again?

Sorry for the trouble.

Sure, but that seems to be the default directory that was created by the app, do I have to create the folders manually?

[Thovi98]

Is it? If I remember correctly, at installation, you have to choose the directory where you have/want to have your files.
You can try by adding a new library in the settings
