The crash you had at 14:25 is caused by a bug in game code introduced in 3.20 version of firmware. Up to that point you might have noticed that *something* is wrong. Each dice roll gives 3 and the game might crash when getting either Community Chest(your case), Free Parking, or Go to Jail. Lack of dice randomization is most likely the reason of pulling this version of Monopoly's firmware from Stern's website.
