Today I saw this entry in the flagged posts queue:
After inspecting the links it was clear that this was just a seasoned StackOverflow user cleaning up some answers. So I tried to flag "invalid flag". Then this box appeared saying
There are no remaining flags on this post.
And nothing seemed to change.
Can someone help me understand this message and tell me what to do when I see this?
The only (unanswered) question I found on this message is /tools/flagged flag removed but post remains.
