It did fail, because as you see, that edit's track 5 says "Rainclous" ... but https://musicbrainz.org/edit/122458416 was in play to change that to "Raincloud"... so https://musicbrainz.org/edit/122458694 failed because two edits wanted to change the same medium at the same time.

They got the change made later in https://musicbrainz.org/edit/122791893
