OP

Quoted from PinMonk:

All it means is now that Stern has washed their hands of the problem in the crappiest, most flow-killing way possible, people need to take off the bracket with the diverter and elongate out the ends of the screw holes in the bracket to make them more oval so the bracket can be moved toward the front of the playfield a smidge, sliding the diverter arm about 1/4" forward so it guides the ball like it clearly should have from the factory, enabling the ball to make the left orbit completely every time, as it was very clearly intended to.
