Hi everyone!
I posted here a year ago with issues with my Thoro-Bred. I've fixed most of them but in the last few weeks something else has messed up. It will play the first ball, then skip to player 2's 3rd ball (when I'm playing in single player), then go to player 2's fifth, then end without resetting the scores. I've posted a video of my problem on YouTube here:

(It's not changing balls on its own, I'm just doing it myself cause the glass isn't on)
I'll give you more information if you need it, I'm just not sure what you need to know and figure it's probably an obvious fix that I'm just missing. Any help is greatly appreciated.
