No guideline appears if object ball is touching or almost touching the cushion.

I've had this a few times. I go to line up a shot on a ball near the cushion and no guidelines appear, which makes it impossible to tell whether you will hit the cushion or the ball first. Not sure if it's to do with the game getting confused by the white hitting both the cushion and the ball at the same time. Will try and screenshot if it happens again.
