Hello 'O great Solid & Beyond

Something that used to be extremely simple now occurs to be impossible.

Part design -> Sketch -> Rotate entities

Sometimes instead of simply rotating either by angle or by association with a geometric constrain funtion completely destoys rotated 2d drawing. And if that happenes one cannot really accomplish it untill a new file is created & he whole model is redone. Please watch movie I attached.

Any sugestions beside downgrading??

Thx from the mountain ;P
