Superleague.co.uk, BBC, and Sporting-life all give Hughes one of the goals. I've just un-deleted the game on my SKY box and Smith did indeed get all six and a drop goal equalling 18 points for the game.
We can't undo the round now but we'll look at possibly giving people the relevant points by adjusting their scores.
We are only obliged to check and rectify errors posted on this thread by the requested deadline. Technically, the issue wasn't raised on this thread until after the deadline as requested, however, we will try and make the relevant adjustment.
