Michael Dobson's 77th-minute drop goal stunned Warrington to cap a magnificent 23-22 comeback by Hull KR at MS3 Craven Park.
A week after coming from 14 points down to beat Hull FC at the Magic Weekend, the Robins rallied from 22-6 behind to seal their third successive win in dramatic fashion.
Dobson was the hero as he has been so often during his time at Rovers, and the stage was set for him after directing Rovers back from the dead for the most unlikely of wins.
For the second successive week Hull FC saw victory snatched away from them in the final minute as a late penalty from Tom Makinson meant St Helens grabbed a point in an 18-18 draw at the KC Stadium.
Having lost the Hull derby in dramatic circumstances at the Magic Weekend, Hull again missed out but can console themselves at least with a point from a game they had enough possession to win twice over.
A dramatic last-minute try from full back Cameron Phelps gave Widnes a shock 26-22 victory over Huddersfield to end their eight-match losing run.
Widnes had led from the third minute of the game after a three-try opening blast in the first 11 minutes to lead 16-0 but fell behind for the first time in the match at 22-20 with just five minutes remaining.
But in the dying seconds Rhys Hanbury's kick hit the post and full back Phelps dived on the loose ball for the match winning try to which Patrick Ah Van added the conversion to seal a memorable win.
London Broncos sank to the foot of the table after going down to a seventh consecutive defeat with an insipid display against Wakefield, going down 24-6.

Wigan effortlessly overcame the absence of a full pack of forwards to humiliate defending champions Leeds 50-8 and consolidate their place at the top of Stobart Super League.
The Warriors were in ruthless mood, much to the delight of Wigan fan Rio Ferdinand, who was among the 16,113 Headingley crowd to marvel at the skills of Sam Tomkins and company as they stretched their team's winning run to 11 matches.
Wigan may have had six regular members of their pack missing through injury and suspension but that not stop their remaining forwards scoring their first three tries of a fierce and occasionally spiteful Roses encounter.
Leeds were simply outclassed by their opponents and, after a second consecutive home defeat leaves them languishing in seventh place.

Ryan Hall's brace for the hosts was the scantest of consolations.
Salford claimed their second big-name scalp within a week with a sensational comeback 34-30 victory over the Catalan Dragons.
Salford followed up their Magic Weekend win over Huddersfield by denying Catalan the chance to move into second spot in the Stobart Super League table and continue their own push for a play-off place.
The Reds looked down and out as they were blitzed in the opening exchanges and conceded four tries to trail 20-0 after just 24 minutes.
But the hosts then scored 28 points without reply, despite being down to 11 men at one stage, as Daniel Holdsworth and Vinnie Anderson were both sin-binned for dissent by referee Steve Ganson.
Then in a frantic finale Catalan looked like getting the upper hand when Remi Casty touched down.
But back came the Reds and Jodie Broughton's second try of the game on 70 minutes, converted by Holdsworth gave the Reds an eight-point cushion which meant Vincent Duport's late try was not enough for the Dragons.
