After giving an answer to this question, the author edited the question. Now my answer doesn't apply and I received a comment from another user that it isn't consistent anymore. The author is most likely either not interested in the answer he was looking for, doesn't visit SO, or whatever. The problem is that my answer is left as accepted and I am obviously getting downvotes for it from other users (well the downvotes are justified since the answer isn't consistent anymore).
What would be the correct solution from my side since I cannot delete the answer?
