Seems like across the nation thousands of people eligable to vote were turned away from pooling stations.

I would guess that if any of these are in areas where the seats were gained by a very small amount then the runners up will have an argument about "they may have won the seat if only"
One of the problems seems that because of the high turnout polling station ran out of ballot papers.
I think 15hrs is a too short an amount of time to vote and this should be raised to 36 or 48 hours rather than the " I want it now" type of voting.
