NZX50G 26 April contract

Aplogies for asking twice, one via the general query form and once again here.
According to NZX and IRESS the index closed up 0.97 at 3520.8. However the contract has been has been closed off at nil price implying it was down.
Can this be clarified please?

It also means the starting level for tomrrows contract is wrong
At 17.00.03 the index was 3516 - down on the day.
However at 17.01.03 it was calculated as 3520.8 which is up.
The index does get calculated late sometimes which I think is due to the actual match time for some stocks not being the same. It has happened in the past and swung the close from down to up and vice veras - last week in fact. But Ipredict has always taken the final level, just not in this case. Or am I missing something?

Yes, I was one who benefited from this mistake, having bought short. Just before close, the index went up and over the line - this was not reported on NZX.com until very late - about 6pm (an house after close), whereas other sites were showing the last minute lift in real time. NZX.com states that the index data is 20 minutes behind real time.
I was tempted to buy a whole lot more short stock after closing, but thought the better of it.
Does iPredict rely on NZX.com + 20 minutes to determine the final position?
