AttributeError: 'SimplePolygon' object has no attribute 'to_simple_polygon'

The last error can be fixed by removing 'to_simple_polygon()' in 'ihp-sg13g2/libs.tech/klayout/python/pycell4klayout-api/source/python/cni/polygon.py' to this:

def moveBy(self, dx: float, dy: float) -> None:
        movedPolygon = (pya.DTrans(float(dx), float(dy)) * self._polygon).to_itype(Tech.get(Tech.techInUse).
            dataBaseUnits).to_dtype(Tech.get(Tech.techInUse).dataBaseUnits)
        shape = Shape.getCell().shapes(self._shape.layer).insert(movedPolygon)
        self.destroy()
        self._polygon = movedPolygon
        self.set_shape(shape)
        self.addShape()

That seems to fix the generated .gds, but not sure if it breaks anything else.
