Export of album.nfo to library folders:
I have some multi-disc albums where each disc is in its own folder.  It seems like in Kodi 17 album.nfo was written to the first cd folder, but in the Kodi 18 1013 test it's written to the common parent folder.  Is that by design?

Yes. I think that makes much more sense since it applies to the album not to the individual disc.

Not meaning to nag, but did you get my PM? I am just concerned that communication is not reaching you, no worries if it is but you don't want to respond but do let me know that.
