I answered a question on Stack Overflow and was submitting a revision to my answer, and got an error saying the page could not be found, and the question had disappeared. I've looked around here and see the 2 most common possibilities are that the question was merged or deleted.
Problem is there is nothing to indicate which happened, and if it was indeed merged, there is no way of knowing where it is now. This is surely a bad design.
If a question is deleted, surely it should show a message indicating this for at least a few minutes, and/or notify the person who originally asked the question (not me in this case) or if it was merged, it should redirect to the question it was merged with?
The data doesn't need to be kept permanently but at least people who are directly editing an answer or doing something on the question could be notified?
