Four manic, second-half minutes saw Charlton surrender a two goal advantage as they drew with Yeovil Town at Huish Park.
Chris Powell's side were cruising at 2-0 before an own goal, a penalty and a red card saw the Addicks throw away their hopes of returning to London with three points having been forced to settle for 2-2 and a share of the spoils.
Before kick-off Chris Powell made one change to the starting XI which lost at Reading in midweek. Skipper Johnnie Jackson returned to the fold in place of Cedric Evina who dropped to the bench.
But the big news was joining Evina on that bench.
There was an early Christmas present for Charlton fans in the form of Chris Solly who was named amongst the seven in reserve.
The reigning Player of the Year was back in a matchday squad for the first time since the 2-2 draw with Barnsley in August after regaining fitness following a troublesome knee injury.
And his inclusion on the bench would give the Addicks' travelling faithful a huge lift pre-match as word of his involvement spread.
Charlton started the game on the front foot, winning a corner as early as 90 seconds into proceedings.
Dale Stephens stood up to deliver the first set-piece of the afternoon and his stinging ball in was nicked off the head of Lawrie Wilson at the near post.
The opening exchanges to'd and fro'd with both sides exchanging possession through misplaced passes and clumsily conceded free-kicks.
And it was 14 minutes before either side had a shot in anger.
Yeovil's John Lundstram, on loan from Everton, fired in an effort from 30 yards which dipped just over the bar leaving the Charlton fans sat just behind it with their hearts in their mouths.
And two minutes later, the Glovers had Ben Alnwick worried again, and it was another loanee who threatened.
Ishmael Miller, leant to Yeovil by Nottingham Forest, stole into the box from the left, but his low effort was relatively tame, allowing the Addicks' stopper to collect safely.
It was a good spell for the home side who were growing in confidence while the visitors struggled to make an impact at the other end.
Indeed, when a hint of an opening did come, a poor refereeing decision stood in the way.
With Powell's men spreading the play wide, Jackson was fouled in the centre of the park having played the ball to the advancing Cameron Stewart on the left flank.
But as Stewart collected with space in front of him, Mr Pawson pulled play back to award the free-kick when Charlton would have profited far more from the advantage.
And the referee continued to cause controversy throughout the half, missing obvious fouls and awarding free-kicks for, on occasions, seemingly nothing, much to the derision of both sets of players and supporters alike.
Although Yeovil's half-chances were coming from range, they were, for a stage, looking the more likely.
A pair of efforts from Liam Davis saw the ball fly straight at Alnwick, and then over the bar as the Glovers' shots tally increased.
But just before the half-hour there was a far more impressive pot-shot at the other end.
Stewart, who has scored his fair share of screamers this term, cut in from the left before unleashing a curling effort which looked to be heading for the top right-hand corner but for a fine save from Glovers' custodian Christopher Dunn.
It would be a dress-rehearsal for Stewart who, with 37 minutes on the clock, gave the visitors the lead with a vicious shot from just outside the box.
The Addicks broke swiftly away from Yeovil's attack, with the Hull City loanee taking the ball over the half-way line.
Charlton attacked three-on-three but Stewart, with Simon Church and Yann Kermorgant for company, decided to go alone, confidently rifling into the bottom right-hand corner of Dunn's net.
Powell's men had come alive, and with that goal, so did Stewart.
The winger had all of a sudden become integral to his side's first-half efforts, as proven by what happened next as they doubled the lead.
Stewart stormed down the left-wing yet again, leaving Yeovil full-back Luke Ayling for dead as he approached the byline, delivering an inch perfect cross to the back post.
And Charlton were spoilt for choice. With both Church and Jackson lurking unmarked, the captain made the call, shouting for Church to duck allowing him to head home the finish to make it 2-0 to the south-Londoners.
The Addicks went into the break with the knowledge that in each of the five games that they have taken the lead this season they have never lost, winning four and drawing once.
Red fingers were crossed with hope that it would prove to be a good omen in Somerset.
Gary Johnson rang the changes at half-time with a double substitution in an attempt to get at Charlton's throats early.
But the first sign of danger did not come until the 54th minute when Joseph Edward's stinging volley only just cleared the bar.
And shortly after, the home side had a decent shout for a penalty when substitute James Hayter apperaed to have been brought down by Dorian Dervite. But Mr Pawson again upset the home crowd by waving the appeals away.
Whilst the Glovers chased the referee, Charlton chased down the other end, immediately coming close to adding a third.
Dale Stephens found himself in possession near the angle of the six-yard box and as he cut his ball back for Jackson Charlton could have had a penalty of their own.
It looked as if the skipper's shot had come back of a Yeovil hand, albeit from close range, as the home side cleared away the danger.
Or so the Glovers thought.
With the clearance falling to Jordan Cousins, the academy graduate powered in a fierce drive from all of 35 yards which narrowly cleared the right-hand upright.
On 64 minutes, the Addicks threatened once more when Church's impressive overhead kick forced Dunn into a low, diving save to his right.
Charlton looked comfortable, but after 72 minutes, things would change.
With the home side advancing down the left, an awkward ball in deflected off the arm of Michael Morrison and into Alnwick's goal.
There was nothing either player could have done, but the Addicks were now under severe pressure.
And that pressure would take just four minutes to give way when Yeovil then won a penalty, and a chance to equalise.
Miller was the man who won the spot-kick after being man-handled by sub Andy Hughes

, and the striker stepped up himself to power in the penalty to level matters at 2-2.
If things had simply gone from bad to worse in a very short period of time, the match's next flashpoint would be best described as a complete implosion.
With a loose ball becoming available in Yeovil's defensive half, Jackson and Ayling competed to get there first. But as the Addick's skipper slid in, he caught the Glovers ' full-back. With the referee deeming the challenge a dangerous one, he brandished the red card.
Charlton were shell-shocked. They had gone from the comfortable position of a two-goal lead, to surrendering that lead, and a player, in just five short minutes.
With that, Yeovil smelled blood.
Hayter should have done better when clean through, instead hitting his tame effort straight at Alnwick before Miller saw a left-footed effort from the edge of the box roll agonisingly wide.
Solly made his long-awaited return with eight minutes remaining joined by Richard Wood from the bench as injury-time loomed.
All of a sudden, Charlton were protecting the draw and that single point, with ten men, suddenly became precious.
The clock ticked down without further incident, and with the final whistle bringing an end to a crazy game in the south-west , Charlton would leave with an overbearing sense of disappointment.
In truth, it was a potentially excellent away victory snatched away via their very own undoing.
