I have attempted to rerun everything in 10 with the same box set, with Musicbrainz and Jaikoz and with both to specific albums. All four times it would not match at all. The thing that seems to happen more often than not has happened again. This album exists in both musicbrainz and discogs. Discogs may have more than one variant. No match. So I wasn’t even able to match and them change file and folder info from metadata in order to force save. I have force saved several smaller albums with no problems.
Sending you the support files shortly. I am not sure if you want to move this to a different topic or not at this point.
