Dice can also not be deduced when you can only move one number because you are blocked on the other, and on bearing off when you don't use the ecact roll. The latter one is only strictly necessary if doing analysis on the dice rolls themselves - an unlikely need with games played here, lol.
There are two reasons why I'd like to see the dice rolls. One is that when I go through a game I want to look at the dice and then see what I would do with the roll before I see the move itself. Having to work out the dice from the move (which is not an at-a-glance operation anyway) makes this impossible. The second reason is that I have a program to download the moves list into a file for analysis but without the dice values it's unreadable by the analyser. I've made it so that the download program reads every game page for the missing (non deducable) dice rolls, which makes it a pretty bandwidth intensive operation.
