Yesterday Question 15411 had a fairly highly rated answer that I thought was the best answer. There was a "please back this up" comment on that answer. Today that answer is completely gone. Is there any way to determine why this has happened, or to request a "re-review"? Or to see an earlier version of the question that includes the deleted answer?
If it matters, the question is how to improve communication to a team leader who asks a question in chat, gets an answer but then asks the same question again. Rather than getting into a long discussion, the deleted answer was to simply send a link to the original answer when the same question is received. This had the advantage of avoiding discussion of who is at fault, and if the original answer wasn't useful, stimulating the conversation about why it wasn't useful.
