Kabongo Tshimanga converted two late penalties as Swindon snatched a 2-1 win at home to 10-man AFC Wimbledon.
The Dons looked to be cruising after Marcus Browne slotted home after the break, only to drop points late on from a winning position for the third game running.
A brilliant save by Connor Ripley kept out a dinked effort from Callum Maycock after a fine build-up by the visitors.
At the other end Paul Glatzel forced a point-blank save from Owen Goodman, who then kept out the rebound from Joe Westley before defenders stopped Glatzel pouncing.
The Dons went ahead 11 minutes after the break when Browne hammered home after Ripley had kept out his first effort and Josh Neufville hit a post.
Ripley then pulled off another superb save to stop Browne's fierce near-post header from James Tilley's pinpoint cross.
But the game turned on its head at the death.
First Joe Lewis tugged down Harry Smith in the 90th minute and Tshimanga blasted home from the spot.
Goodman kept out two near-post efforts as Town pressed before John-Joe O'Toole was dismissed for a second yellow for handball and Tshimanga fired home his second penalty five minutes into added time.
