I posted an answer in response to What will happen if I do not attack Sephiroth on the final battle?
There is now an outstanding post that proves my answer is incorrect. I tried to delete my answer and am greeted with "You cannot delete this accepted answer".
Now what is the point of this feature, as this is now confusing to anyone who reads that page? The only other option I can see is to edit my answer saying this is incorrect please ignore, or copying the correct answer from the other post.
What is the best action for me to take in this situation?
