Hmmm... I think my game is glitched. In 3.1 running robbers, Luis disappears. I think he falls into a crack before I see him. Even in your game he flashes back on screen just before you catch him. In my game he does not come back so I can't get 100%. Sigh.
Well I finally beat it. After many attempts, I waited a full 10 seconds at the start line, then late in the run Luis appeared above me and literally dropped on me out of the sky, completing the run. Very buggy. I'm sure they'll fix it in an update.
