@Shroomir - I dropped the ball nice and slowly and carried on expecting the ball to be good and got around and the ball had drifted just enough not to be able to push it. If I would have been watching the ball, then I would have pushed it sooner. Here's my quick attempt to stabilize the ball Spoiler: Better?
Spoiler: Ball first time i moved it early and it rolled back so could not win. Second start I didn’t push it till B was in place and it was ok then. @Shroomir : ball problems?
