OK, I played the scenario "A Bridge too far" and there is a "dry riverbed" running across the map in front of the village you have to seize. A "previously ambushed" destroyed Humvee is in there too .. but the strange thing is, neither Infantry nor any Vehicle can cross this "dry riverbed" ?? And it just looks like the other terrain with bushes in it and no steep slopes - I looked in the scenario editor and the height difference is I think 17 to 20 - so does this height difference already define unpassable terrein ?
Same thing after I started the "Perdition" Campaign - in the first map there is a dry wadi or something running to the right of the main road and it looks like a very mild depression but again is unpassable for infantry or AFVs .... this just doesn't seem right !
