when holding cmd down on a “smooth” point, tangent points are smooth points, will not move the bcp(s) but only the anchor points across the angle of the bcp(s)

a small script that “corrects” wrong smooht points by toggling the smooth flag of each point

# get the current glyph
g = CurrentGlyph()

# loop over all contours
for c in g:
    # loop over all points
    for p in c.points:
        # deslect all points
        p.selected = False
        # if the point is an off curve don't do anything
        if p.type == "offCurve":
            continue
        # if the point is smooth
        if p.smooth:
            # set smooth to false
            p.smooth = False
            # select the point
            p.selected = True


# get the naked selection object and toggle the smoothness
g.naked().selection.toggleSmoothness()

# whoehoe, done
g.update()

good luck
