You are using "On Nth touch end". N here is not touch ID, it's the index! For example, if 3 fingers are touching the screen and you lift one finger, "On 2nd touch end" will be triggered.
In your case you need "On any touch end" and then compare touch ID.
Or simply use "On tap AreaSprite -> Buster Find path to (touch.x, touch.y)". That's it, just one one event, no need to deal with all those variables!
