I may try it later, but you may want to comment out the line by putting // in front of it instead of deleting the line. I didn't get much use out of this plugin since it doesn't work with pixel movement (decimal coordinates)
I actually tried to get it working with pixel movement by rounding the destination coordinates to whole numbers, and it would work a couple times before inevitably crashing when it tried to go to a node with a float coordinate along the path to the destination
