Rhino6 NurbsCurve Weights Bug?

In Rhino 6 “rs.AddNurbsCurve()” doesn’t seem to behave the same way as it did in Rhino 5 when dealing with weights.

Can someone confirm this is a bug? or am i missing something?
I have attached the GH file. In Rhino 5 It works as intended.

Guess i’ll use Rhino Common instead of rs.AddNurbsCurve

import scriptcontext
import rhinoscriptsyntax as rs
import utility as rhutil
import Rhino

pts = ([0,2,1],[5,10,10],[10,1,0.5])
points = rhutil.coerce3dpointlist(pts, True)

knots = [0,0,1,1]
weights = [1,1,x]

nc= Rhino.Geometry.NurbsCurve.Create(False,degree,points)

for i in range(nc.Points.Count):
    nc.Points.SetPoint(i, points[i], weights[i])

a = scriptcontext.doc.Objects.AddCurve(nc)

@dale Does RhinoScript “rs.AddNurbsCurve” need to be updated to match the result coming from common (which matches the GH “Nurbs Curve PWK”)?
