As far as I can see, this question hasn't been asked yet:
Let's say I've found the safe and revealed 5 of the 6 rooms for the combination, which consists of 1, 2, 3, and 5. So far, I've cracked 1, 2, and 3.
Another character subsequently reveals the 6th room, which has a combination value of 1. Does that room get a cracked token automatically or do I now have to roll a 1 another time in order to crack that room?
