I'm cleaning up a #Grand Prix, and I've ALMOST got it back 100%. BUT (there's always a but) I've stared at this one glitch so long now that I can't see the forest for the trees. At startup, and every ball after, the left bonus double clutches and starts off at 10,000. I've also noticed that when I hit the left outlane, or the left side Advance Bonus sling, the outhole kicker cycles (as if it was serving up another ball). They both advance the Bonus one step, as they should. If you collect the left bonus during a ball, the bonus resets as it should, no double clutch.
I'm convinced this is a simple fix, but it's eluding me. I've traced back through every circuit I can find, but no luck.
I look forward to someone making me say "DUH"!
