What Happened Here? Voted to Close 4 Days Ago, but No Close Votes Today?
The question What are software practices in mission-critical industries (e.g. nuclear power plant)? currently shows a single close vote, but clicking the "Close" link says that I've already voted to close.
Clicking the Edit link shows that the question has been closed twice and reopened, but doesn't show me as one of the closers.
Just curious - what's going on with this, and how can I see the "real" history?
