I have now modified the way Level X games are replayed. It means some changes in the code regarding animations. I have tested what I could and don't believe this will cause any bug, but if you see anything wrong with your Level X games, that's probably a consequence of this change. Please let me know ASAP if that happens.
In replay mode, dice grouping is now shown for the secondary player. You will therefore see that the 2 sixes were put in the same box in your game.
Now, was there a bug? That's another question. As I said above, let me know!
