Hmm, I think you don't use the Pin Behavior correctly. You don't have to pin on some image point, first you set up the position of the child object (the one that has the Pin Behavior) in relation to the parent and then you "fire" the "pin to" action. You can either set the initial position manually in the level editor, or with actions, just like in our example.
Please, re-download the last example, I've updated it to include the Pin Behavior. I used the Sine Behavior on the Enemy objects just to give some motion and pruve that the spawned object (Sprite1 or 5 or identity crisis ) follows.
No need for anything, I am glad if I was helpful, by helping others I also learn my self!
Tell me if everything works ok now
