Collectibles

I have finished the game and found all the handprints. However now I can't move forward because in the extras, it will not let me place the roof on the house in collectibles. Therefore I can't finish the bonus section. All the other handprints moved over onto the board except the roof. Why?!

This is exactly my problem as well! Were you able to find anything out that allowed you to progress? This was a great game with awesome extras and I want to keep going.
