Finally! I managed to figure out what I was doing wrong. When I calculated the orbital positions on the plane, I was measuring both the perigree axis and the true anomaly from the same reference axis (called k1, 90 degrees from the axis of the ascending node). This was incorrect – in the 3d case I was measuring the true anomaly from the perigree axis, as I was supposed to. Just one tiny change, and now everything works!

I knew you would solve it.
