I note that the question about closing questions with bounties has come up on various occasions, with the 'official' question here.
However, I don't think anyone has responded to a little comment made there that one can still go through the entire set of clicks to close such a question, even to the point of selecting which site to migrate a question to, before being told "you can't close questions with open bounties".
I just ran into this behavior in an attempt to suggest this question belongs on a different SE network. It doesn't really hurt me personally if I can't today, but the overall mechanism seems to be an overlooked bug. I figured I'd ask about it in case there is something I'm missing about why it's possible to go all the way down the rabbit trail before being told "sorry"; surely the "close" functionality should just be made impossible during a bounty, if that is the official policy?
