Movement dices are located right below the main board (map) to the left of the "Wound bowl". You just need to hit the button a number of times = to your hero movement dice value (printed on your hero card) and they'll appear and automatically roll.

I suggest to keep the game-chat visible so you can see the results there instead of panning the camera up and down to see where you can move.

I still have no idea where the dice are. Has this changed over the last year? Also, How do you move the player boards for each player? They drop over the chest and I can't move them.
