According to the FAQ, it requires 5 close votes to put a question on hold. This question only has two listed. Why is it on hold?
As a moderator, my vote immediately takes effect, even if there aren't enough votes already. Frank voted to close, and it was waiting for 4 more votes. I voted to close, which was a deciding moderator vote, and the question became closed, listing previous voters and me.
As for why I voted to close it, it's because Frank has it exactly right. This question is not answerable by in-game plot or resources, and is only answerable by a developer. That is a clear close, based on our site precedent.
To add to Strix's answer: There are three other scenarios where a question may be closed without the requisite 5 close votes:
If the OP of the question confirms a duplicate by clicking the 'Yes, my question is a duplicate' button whilst there is a close vote against their question.
The question will show as being closed by the original Close Voter(s) and the system user 'Community'.
If the OP themselves manually close their question for any reason by clicking the 'close' button on their question.
It will show their name in the list of Close Voters
If someone with a Gold Tag Badge for one of the question's tags votes to close. Gold Badges are awarded to users with 1000 votes on 200+ answers in a single tag, so anyone with this privilege can generally be assumed to know what they're doing.
This doesn't happen often, there are only two users on the site with Gold Tag Badges, both are for Minecraft, and one of them is a moderator anyway. But it can happen.
