Assigning new instances of sprites to new instances of other sprites is something I've never done. Deadeye and Doppel should be online shortly - they'll probably have some advice on where to begin.
EDIT: Yeah, I'm not even gonna try. I nuked the .cap making my own events. What my method would be, not having done it before, involves assigning all new instances of the sprite and its colliders an instance number, and modifying my events to run commands on like objects.
