I was not having an issue for the first couple months, but recently my balls are always getting stuck on magnet.
Have an LE with latest code too.
I will have to test things out when I get back home, but just wanted to share that I now have the issue.

Had area around optos cleaned and realigned a little, but problem still happens, but not consistent. Used to never happen on my LE.
Hard shot, both balls get stuck on magnet, shaking machine does not dislodge, third ball does not kickout, I watch my ball save disappear and sigh.
Optos check out fine in test and using ball in hand and sometimes during gameplay.

Game has been in same spot for playing, so I do not think it is stray light causing opto issue. No sunlight ever hits optos.

Will try to pay attention if I am holding a flipper or what mode I am on. Maybe stray light from a certain running mode, but doubtful.

Game does not get played a lot, so I don't think things should have moved around from vibration yet from ship shaking, but maybe.

I think there is a timing issue on how fast you can repeatedly hit vengeance. Hit it too fast twice and it will not register second hit. This during any vengeance mode. It is unfortunate, but hopefully it will change in the patch. Has been like this on all games I have played. Pro/LE.
