I was attempting to vote to close a question as a duplicate, but when I tried copying and pasting a link to the duplicate reference I somehow got the link wrong. Seeing this I retracted the vote to close, intending to try again; but I am not allowed to cast the vote. What can I do now? And, since retraction causes me to lose my vote, what could/should I have done to correct the duplication link?
I have no definitive proof of what I am about to write and I might be a bit rusty on the details because it's a situation that doesn't happen that often.
I vaguely remember that if you retract a close vote it is gone. I am not aware of any way to get it back. A small caveat might be that the question is closed, then reopened, and then you might be able to cast another vote. But no guarantee on that as there are also built-in measures to prevent open-close ping-pong.
When closing with a duplicate question, you'll typically get a preview, so please check this carefully in order to avoid these situations.
I think it was a good idea to retract the vote as it avoids that others will have to check something that does not apply. Additionally it prevents that the question is closed for the wrong reasons.
I suggest for situations like these, that you post a comment akin to the one that would normally be generated automatically. You have done so, which is good, but it might still get unnoticed.
Please raise a custom flag with the link to the duplicate question, so that the moderators can handle this on a case by case basis.
