One extra meeple of MrNumbers got stuck on a long road in the north during quite a long time as well...in the end I completed that road giving MrNumbers 9 points extra and releasing that meeple but it joined my farmer with another with gave me the upper hand in the 12-points farm. Not sure if that was such a great move.
That move gave you exactly 1 point: you took from me 6 points for the farm, but gave me 5 additional points for the road plus released my meeple. But I already was in terrible position, so this meeple (released right before my last tile) didn't give me any significant advantage.
