I checked the FAQ but it just suggests that my answer did not fundamentally answer the question. The deletion confused other commenters as it meant context was lost.
Here is the edit that George made on your answer. In the Moderator Dashboard, the moderator who deleted the answer would have only seen the text highlighted in red, unless he expanded the window. At first glance, no additional investigation seems necessary, since the text clearly seems to indicate that a non-answer was posted.
