I have found a game breaking bug that I think could be easily fixed, should we be allowed to choose/change the ghost we are racing. On level 8 canyon I revived with an advertised checkpoint and have beaten the first 2 staff ghosts. Now instead of racing the 3rd staff ghost (rob) I am instead racing my own pb ghost that revived at the checkpoint. As soon as it revives it glitches out and causes my game to lock up to unplayable. I have tried 3+ times, reset the app, open and closed the app (which allows it to stutter forward very slowly for a second before locking up again) and each time I try to play it continues this. Please look into this. Thank you.
