A moment ago I voted to close this question as I found it to be off-topic. When I got there, there were 2 votes to close as "Non-Constructive" and two votes as "Off Topic." I cast the third Off Topic vote.
I expected to find the question closed as OT, since I had cast the 5th vote and it was a tie-breaking vote. But in fact, it was closed as NC.
Why was this post closed as not constructive, rather than off topic?
Not sure if this is a feature or a bug, so I'm asking.
