I don't know why you are using polygon---I just took it out since it broke the model. It makes something with zero thickness so it makes no sense for a 3D model. If you need something like that perhaps linear_extrude the polygon to some thickness? For the other matter, if you want to understand the problem, examine the BOSL2 manual for path_sweep. There is a discussion there about profiles crossing and how the result will be invalid. It looks like yours is a case where you can simply substitute path_sweep2d.
