Hi, I tried the sunken highwalls walls from buddybud today and i'm having some problems with the transition pieces. I am using the 14m Road Hole Digger, diagonal wall fix and a slope mod. The terrain at the slope always cuts over the walls. It works if i put the top side at the bottom but i wanted it the other way like in the tutorial contained in the package. I tried 2 different slope mods, different heights and without the diagonal wall fix put nothing helped. Here is a picture to show you the problems with the terrain. http://img144.imageshack.us/my.php?image=problemsw9.jpg
