Not only that but I just realised I outdid myself by saying “errorneous redundant”. So not only was “errorneous” erroneous (let’s forgive my not using an adverb for the moment), but since redundant already implies that it was needless/superfluous, I was also, ironically, redundant in my wording.
So ... maybe have another look at the matter just to check if the thing you were referring to is actually redundant? Who knows, it might have truly been erroneous to call it redundant ... or at least you could claim that's what you meant all along :)
