How many people here play that an exit card from the catacombs must be used? How many play that the exit is marked but can be ignored to continue onward in the catacombs?
??? I haven't the card here right now, but we play that if you find an exit you MAY exit, as you can continue inside catacombs if you wish. And what do you mean by "the exit is marked"? I haven't seen any rule about marking the exits.
Anyway, we play this way: if you want to exit, then exit. If you want to continue, go ahead, no problem (and I think that is according with rules).
I'm two steps from salvation, but I'm only taking one. Pardon me.
Wasn't so much interest in the rules... just the common discussion point of choice I heard about elsewhere. Some groups are using a forced exit because they say the movement mechanic for choosing the deviation direction is making it too easy to get to the treasure chamber. Haven't noticed that myself, but thought I'd bring it up.
