Not really a problem, but maybe something you want to patch up.
While the AC is running, a RMB and column edit (like Empty Column) unlocks editing on the rest of the data.
Although it’s done this for a while - and I kept quiet cos I like to edit during AC - it really causes problems now. A lot of fields that were edited during AC (both by the user or the AC) will be blank. This isn’t apparent until you re-open the files that you just multi-edited and find a lot of blank stuff.
Some may get mad at me for bringing this up, but you’ll be even madder if you look back at your collection and find a bunch of empty tags.
