Debug.DrawRay not drawing since upgrading my project to 3.3.*

I can't get the following code to render any Debug.Draw* code in my project. I had verified it working in a previous version of unity (same project). I am getting the "HI" output to the console, so I know the code is being run, but no rays. Before anyone asks, it is in the Update() method of my script.

Debug.Log("HI");

Vector3 forward = transform.TransformDirection(Vector3.forward) * 10;
Debug.DrawRay(transform.position, forward * 10, Color.green);

Thanks.

Works fine in 3.3 here.
