I've noticed the same thing with the ground as well as solid objects such as the floors of buildings. I think one thing I figured out is when creating the object, it actually has to be flipped 180 degrees. Here's an example:

Let's say I create a block (such as the floor inside the large building) and I give it the length, width and height. When entering the height, it actually comes UP from the z axis. Now most people know that NPC's in Emu ignore walls, trees, etc. So when spawning the NPC, it's actually going off of the original z axis that the block was created from, ignoring the "height" at which I put the block. To remedy this, I'm trying something new. When creating the block, I'm actually flipping the block over 180 degrees after creating it so it puts the z axis of the block on top instead of the bottom. Hopefully it will spawn the NPC to actually stand ON the block instead of IN the block.

I'll post results when I'm done testing it and if it works, I'll flip everything 180 degrees and reposition. Then update the download. As far as the ground, I'm at a loss with this. Maybe Windcatcher has an idea or maybe it's something he'd be willing to look into.
