Is this some kind of default map or a terrible template? Because the random generator doesn't place tent guards at passages, and you can't blame SoD for that anymore. And in general, absolutely unused and banned objects (cartographers, obelisks, hillforts, etc.) should be removed entirely (except for Anarchy). On this point, I disagree with those who will start shouting about changing the original meaning; if an object cannot be used—it is not needed—then it must be removed.
