Bug V6 : rotate control point

Attached some pics to explane my problem.

As usual when I stretch surfaces by control points, i try to match continuity by rotating points, but in my actual version of rhino WIP (6.0.16264.10331, 20/09/2016) Beta , it seems doesen’t work

maybe i’m wrong, but i think it’s a bug

thankyou all

Hi Simone,

Might this be related to rotate not working in the latest wip:
