Activedoc.Objects.AddMesh - Broken in latest Rhino 6?

I think I fixed it. This wasn’t necessary in Rhino 5, because Triangles are represented as 4 vertex polygons, where C and D are the same, but I guess this has changed in Rhino 6?

        public static Mesh PlotMesh(PachMapReceiver[] Rec_List, System.Drawing.Color[] C)
        {
            Mesh MM = Hare_to_RhinoMesh(Rec_List[0].Map_Mesh, Rec_List[0].Rec_Vertex);

            if (!Rec_List[0].Rec_Vertex)
            {
                Mesh MF = new Mesh();
                for (int i = 0; i < MM.Faces.Count; i++)
                {
                    if (MM.Faces[i].IsQuad)
                    {
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].A]);
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].B]);
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].C]);
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].D]);
                        int f = MF.Vertices.Count - 4;
                        MF.Faces.AddFace(f, f + 1, f + 2, f + 3);
                        MF.VertexColors.SetColor(f, C[i]);
                        MF.VertexColors.SetColor(f + 1, C[i]);
                        MF.VertexColors.SetColor(f + 2, C[i]);
                        MF.VertexColors.SetColor(f + 3, C[i]);
                    }
                    else
                    {
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].A]);
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].B]);
                        MF.Vertices.Add(MM.Vertices[MM.Faces[i].C]);
                        int f = MF.Vertices.Count - 3;
                        MF.Faces.AddFace(f, f + 1, f + 2);
                        MF.VertexColors.SetColor(f, C[i]);
                        MF.VertexColors.SetColor(f + 1, C[i]);
                        MF.VertexColors.SetColor(f + 2, C[i]);
                    }
                }
                return MF;
            }
            else
            {
                MM.VertexColors.SetColors(C);
                return MM;
            }
        }

Thanks!
