I just answered a question on Stack Overflow here.
If you look at the history of the question my answer stands OK. But now the OP has changed the question due to some unknown reasons. Due to which now my answer has no link to the question.
So in this case should I delete the answer or wait for OP to make a correction to his/her question?
EDIT:- A user named MAT has now reverted the question to the original one. But I still wanted to know what should one do if this happens in future. I know as a disciplinary action one should delete the answer in that case, but what if the answer was OK for the original posted question?
