Royal Wootton Bassett Town passed up the opportunity to move back into the Hellenic League Premier Division playoff places as Slimbridge snatched a dramatic point courtesy of a stoppage time equaliser.
Despite falling behind early in the second half, Sam Collier's side appeared set to complete a season double over the Swans - and to climb above Highworth Town into fifth in the table - courtesy of a pair of quick-fire goals from Chris Zebroski and Brad Pagliaroli.
But Toby Soule scored at the death for the visitors to make it 2-2.
When the two sides met in Gloucestershire earlier in the campaign there was plenty of early drama with Bassett scoring four times in the opening quarter of an hour on their way to a thumping 6-3 win.
The return fixture was much more of a slow burner in comparison. Indeed the first half passed without much incident.
Drama was on its way following the restart though.
Slimbridge would take the lead on 52 minutes as Joe Hunt connected with a Soule free kick, heading beyond James Foster in the Bassett goal.
But Bassett soon turned the game around.
With quarter of an hour to go, Zebroski planted a firm header into the back of the net from an inswining Pagliaroli corner.
And within the space of two minutes the hosts were ahead. Alfie Presley surged forward before squaring to Pagliaroli, who fashioned the space he needed to shoot before arrowing a fierce 25 yard drive into the bottom right corner, beating 'keeper Travis Wood at the near post.
While not at their best, Bassett seemed set to hold on for all three points.
However, Slimbridge salvaged a point ninety seconds before the final whistle.
Foster could only parry from a Rhys Sarson shot and Soule was on hand to put away the rebound.
