> In this case it was simply a copy paste error which they pointed out.

Right and life went on before you decided to play "hero".

Others? Just you. And it's rather childish to "appeal to downvotes".

"Yeah, no."

Listen, the only one causing drama here is you. I made one innocuous and helpful comment. The guy responded and everything was settled. The conversation had nothing to do with you and yet here you are.
