bug status-reviewstatus-completed
Verified in first answers, not sure if it holds elsewhere but I imagine it does.
I stumbled over a link-only answer, and my first instinct is to downvote and flag. Voting is fine. The flag menu, however, acts as if the post is deleted (which, in this case, it was), only giving "in need of moderator intervention". Only deleted posts give one option, which is a dead giveaway that the post is an audit.
Aside being a dead giveaway that the post is an audit, combined with the lack of being able to flag and then go on to "I'm done" means there's not a sane way to end the review, even if the flag dialog was present. I've flagged a couple real answers and I have no idea what to press afterwards. There's no applicable feedback, "looks OK" is wrong, and so is edit. Allegedly, this part is supposed to be fixed, but I don't see any change in the available options, and flagging isn't enough to complete the review (which is a massive regression, in my opinion. You used to be able to vote and flag, and pick "I'm done" to move on).
Ended up clicking "share feedback" just to end it, which also doesn't make sense as a pass case for this particular type of posts given the current feedback options. There's not really any good way to handle audits at the moment, though. Here's the audit in question (10k+? on Stack Overflow), for anyone interested.
