Voronoi Meshes Flipping Direction

I’m having an issue where the Voronoi bumps / mounds in this definition are flipping direction at the edge of the surface. The flip component receiving the generating polylines is telling me “Guide and curve are not roughly co-planar.” Anyone have an idea for a fix (and/or what’s generating the problem)?

Thank you!!

I don’t have your plugins so i just made the part you need.
This uses the first 3 points of each polyline to create a plane (so if you polyline have concave angles it wont work), then it flip all the polylines to make them go towards a given point.

Aha, this works beautifully. Thank you for the lesson @maje90!! Much appreciated.
