Its not the AI, its the collision detection, in the past I was able to get perfect enemy collision by slicing terrain into 3x3 segments and piecing these together in segment creator since they all shared the same pivot point they would sit perfectly, even now you get reasonable collision with terrain entity's for the player.
Since the introduction of null space in v1.05 to prevent enemies falling off platforms etc you need to slice your terrain into single segment sizes, which apart from being a pain means you cant create anything of a useful size as segment creator crashes if you try to place too many meshes. X10 I believe has exactly the same collision detection for terrain.
Whats really needed is a flag to turn off null space when you dont need it.
