When I open the Flag menu for a question or answer and select the Closing -> Off-Topic I see the next possible flag:
This describes a problem that can't be reproduced that seemingly went away on its own or was only relevant to a very specific period of time. It's off-topic as it's unlikely to help future readers.
IMO this discription is very useful but it doesn't fit on the off-topic at all.
Are you agree? Shouldn't this be moved from there?
