Quoted from DeathHimself:The first is now when the hammer magnet grabs and brings the ball down, the magnet isn't returned as quick as it used to be and the hammer is rising to show the hole in the playfield until the magnet returns.
The second one is during electric chair multiball I noticed that if you are running three balls and lock one in snake it holds the ball and doesn't release it until the other two drain. I know there used to be a slight delay but from what I recall I thought it was only a few seconds.
I haven't noticed any difference in the hammer magnet, other than I thought it was grabbing the ball more reliably than usual, but I think that has to be my imagination or wishful thinking.
I just had Sparky multiball going with 3 balls, shot one of them in the snake, and it gave me another ball immediately.
