I am using a purely Null Terrain-filled map with Creep. The only race used is Zerg. I would like to make it so that units cannot venture into the Null Terrain, only along the spawned Creep. I dont know how to work terrain levels very well (@ all), so thats probrably what could fix this.

this is just a suggestion...but you could try finding a tile that is wall like on it, and border outside of the region you want. a square tile part of of a high terrain like a temple wall, dirt-to-water edges, or something else that makes units can't walk thru it.
or you can put units blocking the way on the edge...
