I recently had a question closed within less than two hours.
Now, I still think, it's a legitimate question so I edited it, adding grammatically correct questions.

I understand that there must be at least five highly reputed people who like a question to be closed before it is actually closed.

Now, when I look in the activity list of those who allegedly closed that question, I can not find their close action, except for two of the five people. So it seems that three of them never closed my question.

Is that a bug or expected behaviour?
