When you use a cubic_spline for a prism, the second vector in the list must
match the second to last vector in the list. (For a smooth transition all
the way around, the first vector should match the third-to-last vector and
the third vector should match the last vector, also.)

For more information on your exact problem see "2.3.1.3.1  Teaching An Old
Spline New Tricks" in the documentation.
