When pulling back info on a closed question, I have come to expect
closed_reason to be a present key if there's a
closed_date. It seems that as of recently this is no longer true.
What happened to this key? I need it. Can it be reintroduced please?
Edit: Just noticed this is still in the API documentation, so I guess this is more of a bug. Again, please add this back to the API. We need it as part of Ask Ubuntu's ongoing cleanup effort.
