(Pathing Issues)
When you aquire the archer creep and they get ahead of the minotaurs they set up a perimiter of there shooting range. An arc of archer is created around there target. Minotaurs cannot figure out how to go through this arc of archers. The do the running animation ontop of the archer but do not go past the archer unit it is dead or has moved. Ill try to make a diagram this is what it looks like. The X's are archers and the Os are minotaurs the T represents a tower the archers are shooting at.
