I've came across this review which I wanted to flag it as not answer, but after it was hanging awhile in my open tab, when I've back to it, it says:
Review completed 24 mins ago:
x reviewed this 24 mins ago: No Action Needed Next
This is not definitely the answer (rather 'I've this too' or a comment), however this post has been marked already as: 'Review completed' despite only one person had a look at it?
Is that an expected behaviour for First Posts queue?
Update: It actually got picked-up again in here (Low Quality Posts queue).
