Yesterday there was a question which I answered, and the answer got two downvotes, so I tried to understand what I was not communicating well. The question was about "energy conservation appearing because of field theory". There were a number of comments to my answer by AccidentalFourierTransform and,I think, GenaroTedesco . Thinking it over before going to sleep, I planned to edit my answer to make clear that the energy conservation law applies to closed systems. When I entered this morning, greek time,the whole thing has disappeared. As a high reputation user I see deleted questions by anybody. This has disappeared completely and not edited to a new format afaik.
Whats up? For us senior citizens where the A possibility looms, it is disturbing to have to start thinking "did I really answer the question, or did I think I did " (joking at the moment as I still have all my faculties intact, but time flies).
