When I manipulate the vertices for the first guard, my plane is no longer flat but moves along the 3 axes. How do I prevent this to keep my plane flat?
I have this problem too, basically when you click and grab a vertice in camera perspective to move it, it pushes into the x or y axis. I think its because of having the camera perspective at an angle. So instead of moving the vertice on a plane, its getting warped.
