title: SKNode follow path is always relative
body: <p>I have a function that creates a path from a sprite and then runs <code>SKAction.follow(path, duration: 1.0)</code>. The path starts at (0,0) and ends at a target point. When I create this path for each sprite and run it, they all move along the same path, but relative to their start position. </p>
  
  <p>They dont follow the path from their position to the same target position for some reason, they dont converge at the end point.</p>
  
  <p>What am I doing wrong?</p>
