David, in the pic the roads covered the shore part of the water tiles...what, lemme see, yeah, the road covers the shore...Atleast I think so.
And to get the units on the water, Yogurt put transport ships on every water tile space and put 1 unit in each. Then he tested it and then went back into the editor. Then he deleted the ships but the units remain. So, he rotated them the way he wanted them to be and there you go! Units on water. (I think that's how he did it)
Oh, BTW, you can't put units on bridges! (I think)------------------
