Missing Gridshell Intersection

Hi everyone,

I've encountered a bit of a problem in making a parametric gridshell. I'm currently trying to find intersections through my gridshell in order to create straight polylines instead of curves and in order to make parametric connection details.

Although currently in "clockwise curve" number 29 one intersection fails to be found, i've tried altering the geometry multiple times and all this seems to do is move where the one missing intersection is. I'm really stuck as to what might be preventing this intersection from being found and it's lack of existence completely messes up my data trees so if anyone could give it a look and has any ideas on where my elusive intersection has gone i'd be really grateful.

Definition, geometry and a picture of the problem are attached :)

Thanks!
