Here are my plugins. I’ve marked those that appear to be not applicable.
Plugins:
Additional Artists Variables
Deezer cover art (n/a)
Feat. Artists in Titles (n/a)
Fix Track Numbers (n/a)
Keep tags
Padded disc and tracknumbers
Persistent Variables
Replace Forbidden Symbols (n/a)
If I were to pick a suspect, it would be the persistent variables plugin. I’m using this in a script to create an ‘album genre’ per this previous thread. @rdswift and I noticed some flaky behavior building my genre script and Bob felt he need to “ponder” the results vis-à-vis his plugin.
Despite those issues, I was able to finalize a script that works well. I do have an occasional album where the genre result is still inconsistent across tracks, but a simple Ctrl-R fixes it. So there is still some weirdness there as in that previous thread.
