Nigel Pearson was left bemoaning a familiar story as Bristol City conceded two soft goals to throw away their lead and leave Ashton Gate empty-handed.
After an uneventful opening 20 minutes, the Robins started to assert their dominance on the game and Andi Weimann went close to opening the scoring when his effort came off the inside of the post following Nahki Wells' delicate flick over the defence.
City's spell of dominance was rewarded on 33 minutes when Cam Pring's pace and power on the flank allowed him to beat Jacob Brown to the byline and flash a delivery across goal. Wells was in the right place at the right time to bundle it in from close range to grab his eighth of the season.
