Ok, got another sesh on the game today. Froze twice, once when the ball was in the back scoop, did not initiate ball search, tilt didn't register. Second time the trough didn't eject my ambush multiballs and when I drained, that was it.
I increased the magnet strength on the Xeno and I sort of got the ball stuck there twice, once clean and once it kind of just bounced back there. This is a timing (game does not register fast enough) and magnet juice issue me thinks.
I also had to do some proper bending and re-align one of the spinners that clearly had a manufacturing defect. The other is perfect.
Beat my GC with 1 million more.
