One of the stupidest mistakes the linesman made was calling Hemmings offside when he was near the half way line when the ball was kicked and they made Lincoln take it from just in front of us, instead of where he was offside near the half way line... That's just basic.
The foul your talking about was ridiculous too, fairly sure the ref actually shook his head initially and then randomly changed his mind despite the linesman being next to it and not flagging to correct him.
