I'm pretty new to Plasticity and just got through the intro-type courses, so forgive me if this is a pretty obvious problem. But I'm trying to loft between this existing face and a new region I've drawn with curves, but I'm only able to achieve G0 continuity from the existing face, G1 or higher gives me this error. I double-checked that all of the points on the curves are directly on top of the vertices they connect to, but I'm not sure what else to look out for that might cause this.
