I cast a close vote on this question: Simplify expression in Swift playground, or at least that's what is claimed and is preventing me from casting a close vote now.
Yet the question appears to have zero close votes cast on it?
I know that if the question were closed after I voted to close then reopened, my close vote would be gone, and this would be correct. And while this question has been closed and (inappropriately) re-opened, my close vote is supposedly after this closing and re-opening occurred.
So, what's going on here? Why doesn't my close vote show up?
(Whether or not the question needs to be closed might be another meta question, so please don't get off-topic with answers here. This question is strictly about a close vote that's not appearing.)
