convert: does auto_keep ignore all other options?

[frigginbrownie]

Hey y'all,

Big fan of beets. Am working on moving my music to a NAS and refactoring how I store my music. My want is:

1. One database, storing the highest quality version that I have.
2. If the file is lossy, import into beets and copy to the \music directory.
3. If the file is lossless, import into beets, copy to the \lossless-music directory, and convert to lossy into the \music directory (for easy playback on devices which don't support higher bitrates/codecs and archiving purposes).

I've played around with the config file for a few days and have half a solution - using the convert plugin with auto: no, auto_keep: yes, and default path set to \music. Importing flac files results in the lossless version being imported into beets, copied to \lossless-music, and converted into a lossy version stored in \music (perfect!). However, lossy files are still being converted by convert on import, resulting in \music having duplicate versions of lossy files.

I've tried setting never_convert_lossy_files and no_convert, but these don't seem to be followed if auto_keep is set to yes.

So.. is something wrong with my config file? Is this a bug regarding the convert plugin? Am I doing something with beets that can't be done?

Included is a snip of my config file and what my current output is. Thanks for any suggestions in advance.
