I had submitted an edit to correct the artist credit on a recording. A few days before it passed, an auto-editor submitted an edit to the same recording to replace "and" with "&" (or maybe the other way around). This resulted in my edit being invalidated, (even though it was still useful), and I would have to re-enter it to get it in.
I'm guessing that this is a known issue with Musicbrainz.
Did the auto-editor get a warning when submitting? Something like "You're about to break someone else's edit. Are you sure you want to do this?"
Also maybe edits that break other edits should be auto-flagged as votable or something?
Should I submit a feature request to add this?
