Fans of 'Survivor 50' are reeling after host Jeff Probst committed a huge gaffe during Wednesday night's finale. In a live production mishap, Probst accidentally spoiled the winner of the vital fire-making challenge, a segment determining who makes the final three. Aubry Bracco was revealed as the victor, with another contestant's fate also prematurely exposed. This 'last twist of the season,' as Probst called it, wasn't supposed to air until later in the broadcast, leaving viewers and producers alike utterly stunned by the live television blunder.
