It appears that if an "Edit release label" (edit type) fails it causes any changes applied afterwards to be removed. Issue is listed here - http://musicbrainz.org/edit/16564445 on release http://musicbrainz.org/release/644c6671-3119-4998-bd7b-d549a105d49a "I added the catalog # and label but both appear to have been removed (i'm guessing) after this failed. It Did show when I added them edit #16576872 edit #16576873 edit #16577034" Part of the edit shows under the label as applied but nothing about the catalog # - http://musicbrainz.org/edit/16577034 Test server isn't cooperating so couldn't verify the exact conditions. (as of yet) Expected result would be that since an Auto-Editor made changes that were applied, any prior edits would fail (dependency?) and all applied changes take precedence and would remain.
