An injury-time retaken penalty sunk Nelson hearts in a game they should have won comfortably.
Chadderton took a 12th second lead through James Curley before Nelson hit back through Jason Powrie onthe half hour mark.
The visitors hit their hosts on the break to regain the lead through Matthew Chadwick five minutes before half time. But Nelson deservedely levelled with a Jerome Matthews (pictured with Powrie) header on 74 minutes.
Nelson bossed the remainder of the game only for Chadwick to net the winner with his late retaken spot kick.
