So I "failed" an audit review, where there was low quality editing. It wasn't spam or anything, at least as far as I could tell with a cursory glance, so I did what I've done many a time - I clicked "Improve".
I was then failed because I didn't choose Reject.
I see this as an issue with the logic - if I had clicked "Accept', sure, but I'd set out to make it better - if I then realised the edit was not salvageable I'd have gone back to reject, normally.
Or am I missing something in my sleep deprived state?
