Thanks, yup definitely a bug, the intersector appears to be having difficulty getting one piece of the intersection curve, you can see this if you select them and run Construct / Curve / Isect to create the surface/surface intersection curves.

Yeah definitely the amount of calculations get more complex when there are more edges and pieces running into each other, particularly if you end up having small fragments involved.

Definitely send these on over when you run into them. Probably for many of them I will have to collect them up and send them to the people that make my geometry library and wait for them to fix them which will take some time. But eventually progress can be made on them.
