Hi Val,

Yup, there is some processing that happens so that you can cut things at a place where a curve crosses itself, and that was picking up the starting point of a closed curve as a self-intersection point. But only in certain circumstances.

Thanks for posting that example file to help track it down, please let me know if you see it happen any more!
