Hi,
Since iTunes 12.4, playlists seems to have changed because Hazel can't read none (t's trying to fetch them but ends up with "No playlist available" and the dropbox is greyed out).
The problem is that I can't apply any modification since Hazel will trigger a "At least one of the actions has an empty field..." error message.
If I remove the "Import into iTunes" action then everything is fine. So my guess is that it does not like the empty playlist dropbox.
Please note that rules will work fine unless edited.
Am I missing anything?
