Hello all!

I've found myself with a most unusual issue. I'm sure it's a simple fix, but unfortunately I haven't been able to devise a solution.

I'm attempting to use HelmsDeepRampart05 as part of a map, and I cannot get the terrain to line up with it is such a way that a unit can walk through it. The unit is either walking on the ramp/gatehouse, or on the actual aground, but cannot effectively transition between the two. Here's a picture to give you an idea:

Any ideas on this one? I've tried leveling the terrain to within .5 of height, a little above, a little below, and as even as possible to no avail. Looking at the actual Helm's Deep map has been no help.

Thank you all in advance!
