I just tried to take down a thread for being on the wrong section. I left a notice to the asker why I was doing this as a comment, and then tried to hide the question. But the site blocked the action and asked me to "please click again to confirm". So I pressed the "hide" button again, but the exact same message appeared when the post loaded again, and there seems to be no way to take it down otherwise. The "flag" button behaves the same way.
It's half an hour later and this message is still appearing when I try to take down the thread. I've tried accessing it through different devices/browsers and all different ways of reloading the page, but it still blocks me with this message repeatedly. I've never encountered this message before: is it a new feature that's not working properly?
EDIT: it seems this message has broken the hiding and flagging systems entirely. A hidden thread was linked in a comment, and we're all entirely unable to reshow it or clear its flags. Nobody has had any luck with the thread I linked either. So this is urgent now: if it's going to be recurring we're going to have an issue on our hands very quickly.
