Llantwit Major were held to a 1-1 draw at Baglan Dragons in the Cymru South after a 95th minute equaliser.
Nathan Logan's last-gasp header denied the visitors what would have been their first away win in the league this season.
Kick off at the Evans Bevan ground had been delayed by 30 minutes due to the M4 being closed between Margam and Pyle in the wake of Storm Amy.
When the game did get underway, Baglan enjoyed the lion's share of possession in a first half that gradually sprung to life.
Kofi Rowe came close for the visitors, outpacing a defender before his effort deflected wide for a corner.
The hosts had just been denied by a fine save from keeper Ryley Allen, when straight from the counter attack, Rowe broke clear down the right flank before his cross was headed in by Jack Bevan to give Major the lead after 40 minutes.
Llantwit pushed hard to kill off the game late in the second half - but wasted at least two chances to add a second goal.
And they were ultimately made to pay for it when from a dubiously awarded setpiece, Jack Fleming's cross found Logan who nodded past Allen deep into stoppage time.
Karl Lewis' men drop to 12th in the table with just seven points from their first nine games, as they prepare to entertain Pontypridd United at Windmill Lane next Saturday.
Ponty go into that game off the back of a 5-2 victory over Treowen Stars on Friday - only their second win in the league this season.
Cambrian United remain top despite a tricky goalless draw at Carmarthen - with second place Trefelin also playing out a stalemate at home to Afan Lido.
Cardiff Draconians' impressive unbeaten run continued with a 2-1 win over bottom club Cwmbran Celtic, who had Andrew Larcombe sent off, while Trethomas Bluebirds drew 1-1 with Ammanford.
Two games fell foul of the weather - Caerau Ely's Friday night clash with Newport City and Aberystwyth's home game against Ynyshir Albions on Saturday.
