Stockport scored an injury-time equaliser against Cheltenham but the match was overshadowed by a pitch invasion that forced the players off.
With five minutes remaining home, fans ran on to the pitch, sat down in the centre circle and refused to move.
Already-relegated Stockport fell behind when Brian Smikle finished from close range after good work from Joshua Low.
When the players returned, Stockport's Greg Tansey scored from the spot after Andy Gallinagh fouled James Wallace.
Stockport County manager Ray Mathias told BBC Radio Manchester:
"Unfortunately today we didn't put one of our better performances in and we didn't get our game going.
"For 5,000 people to come and support a team that has just been relegated is absolutely fantastic.
"They've got a result today, it's not been a win, but delighted to come back in the game and get the draw in the end."
Cheltenham Town boss Mark Yates told BBC Radio Gloucestershire:
"I feel cheated, the referees got a big decision wrong, it was never a penalty in a million years and that decision has cost us.
"That game has summed up our season with the frustration that we dominated the game, created chances and not taken them.
"(Scott) Brown had one shot to save in the first half and apart from that he's not had a kick really. I'm very disappointed with the officials."
