Without going into your post in detail, I think this is the source of your problem. For each group, you're better off making a single object which contains all the elements in it, then making A.group a reference to that object. Start with N such groups, one for each piece. Then, when you connect two pieces, you merge their groups into a single object. Now, each time the user drags a piece, update the whole group (including the piece clicked on) with a single command. Another advantage of this approach is that it makes it easy to do other group-level operations like depth-sorting, and of course the puzzle is solved when there is only one group!
