That's a bug that I was aware of but didn't have time to fix. What is actually happening is, the hero tries to swap places with itself and stays in place, and also, sometimes when 2 heroes swap, the first swaps with the second and than the second swaps with the first... so they stay where they started. When you right click on the dice, it says "Swap all characters... sometimes???". Now it's fixed.
I think all other dice work as the game says. Please let us know if we missed some bugs
