From what I understand from the live stream here is what happened (disclaimer I might have interpreted the situation wrong)
Lachlan did his average as normal but on the second solve he accidentally bumped the cube cover before inspection.
He was given an extra at the discretion of the comps delegates and the solve was given a DNF until it can be reviewed by the WRC
Shortly after this happened while everyone was confused and trying to work out what was going on someone posted the scrambles for the average
not knowing that some people where yet to compete.
So they re-did the round and anyone who can't prove that they did their solves before the scramble leak will have results from the re-do
But anyone who can will have their results from the original.
(I would like to emphasise the fact that I was not there and I am not a delegate so I can't confirm that this is actually what happened)
