I sympathize with the confusion around 11...I remember all those exact thoughts as we ran into all sorts of swamps and lakes we didn't expect
On the bright side, our original course design didn't have CP10. You just went from CP9 to CP11. But we decided that (a) Moon Falls is a cool place, and (b) there are even more ways to get lost in the dark if you go straight across from CP9!
