I like the graphics too, please do make them accessable.
As to the error, definitely not a WAD, more like and SU (Screw Up). It's a map definition error. They put the cut in on the SE side of hex 48,35 instead of NE side of 47,36 where it should be (using Historic Scenario 1.1 map).
And I checked on whether there is a 3D graphic for cuts and found it. You can see it if you go to the railroad cut NE of Gettysburg. The problem is that they emplemented it only as a "Drop", that is, a level change side. Since these cuts are one hexes without a level change it can't display. You also have the problem of a 3D view with only one direction can show the nearer side of a drop that faces the north.
Now to the problem of should the terrain shown here be at a lower level so it would display. Problem is a hex is 120 yards wide and the cut isn't. While it wouldn't hurt to lower them from the cut point of view I am not sure you can from the non-cut directions (NE and SE). In terms of representing the terrain if you have visited this part of the battlefield you know the cut is very narrow and the terrain around it is about the same level as adjacent terrain. But since units in the cut hexes can't really choose not to be seems you could just go ahead and lower the hexes one level.

The Railroad Cut looking west from where Archer got caught in it. Chambersburg Pike is to the left. This isn't the part in question but is probably typical of the size of the cut.
