That horse has definitely left the barn.Well,..... shoot. Ok, so be it. I'm not sure how much that would have changed my defence set up but it is what it is. As long as the LOS for hexesides such as MM40-MM39 and north to MM36 are not blocked by the green in MM39 (as per B10.2 adjacent) we should be good.
I'm thinking the crestline for rivers should have been drawn the same as for hills - the lower elevation water would intrude into the higher elevation land rather than the opposite.
But we're 40 odd years too late for that.
