I was playing Yesterday night (8 to 10pm p.s.t.), and during the game, the Advanced Dice Roller stopped working. I could still adjust the amount of dice, Type of dice & + or - to the roll, but when you clicked on the "Roll" button.... nothing. it had worked for about an hour before it stopped. The "Base Dice Roller" still worked. & the "Re-roll" function on the bottom still worked. My hardware & software: Older IMAC running OS-X 10.6.8, Web browser is Firefox 19.0.2 At work at the moment & unable to re-create the event at the moment. Just letting you know. Thanks,
