there is a situation .. i am not sure which .. when you still have the 'swap dice' link .. but it wont work
i think the situation is when you have 1 piece on the bar and can only move it out with 1 die (the other die is blocked by your opponent) .. the 'swap dice' link is still there .. but when you click it nothing will change
i dont know if the first die has to be the higher or the lower to make this happen .. will see if i can find an example in any of my games soon :)
should i report this as a bug as well ? or is it cover by what is discussed below ?
