Paul McManus's brace was not enough for all three points as Forfar Athletic and Airdrieonians drew.
The hosts drew first blood when Gavin Malin swept the ball past Airdrie stopper Colin Stewart from the middle of the box.
The Diamonds hit back when forward James Lister got on the end of Lewis Coult's cross to head home from close range.
And they took the lead after the break when William McLaren tucked the ball past Darren Hill from the left side of the area, but the lead did not last long.
Substitute McManus's deflected strike drew Forfar level and he then slotted home a quick second.
But the game took another turn late on when Coult's low drive levelled the score again.
