In terms of advantage we took it by running 15m odd, but thats all out the window once it was sent upstairs. A video ref can't rule on advantage and rightly so, he can't rule on anything past the original error in this situation.I guess they can only check when there is a stoppage in play. Regardless there was no advantage to the Warriors. correct decision.
Thankfully Perenara asked for the contest to be checked, because Cummins was going to award the try and rightly so.
Saved by the rulebook!!
