Quoted from Robertstone0407:
I noticed sometimes my magnet will hold the ball and not let go. After about 1 second it does a ball search and drops it
Ok, this happened to me a day after I unboxed my game. After a few more times, the coil burnt and my magnet was scorched. It turns out it was a bad node board (node board 9 I believe) where one of the components activating that coil would "stick" open. This may be related to the issue mentioned with the service bulletin of components breaking or coming loose on the board.
They swapped my board, and because it was scorched, my magnet coil as well.
My recommendation is to turn off the magnet in the menu until you can verify that your node 9 board is operating properly (turning the magnet on and off as it's supposed to).
I was able to test that the component was stuck on with a continuity tester, or at least it seemed that way.
