People asked about other types of flags (e.g. low quality) but I am asking a question about the "Not a real question" flag. I flagged a question as
not a real question. The flag was marked invalid but the question was closed for same reason
How to output the name of an input variable was closed as not a real question
I flagged the question "Not a real question" 18 hours before the question was closed, and the flag was marked invalid.
I guess my question is: How are invalid flags determined? How does it make sense for me to have an invalid flag for a question that was subsequently closed for the exact reason I originally flagged it for?
