I do believe there's a better way to do this. It's just the ground in general. On our Superman, we changed the ground attachment points. i have to take a picture to explain it. but having solid grounds ensures better reliability in general on this game. And if the ground for this one cap is at issue, i can pretty much guarantee other grounds are flaky too. so it's better to fix the entire ground plane, then it is to fix it for just one capacitor.
