Hi there! I could track better the problem and fix it if you answer me these questions:
Did that happened on the results screen at the end of the race or in-game? was it for a moment or it remained bugged until the end of the race? did the results screen matched the places that were just before the race finished? were you playing for a long time? how many laps and players?
If you could answer me or somehow reproduce again the glitch and give me more details I would be appreciated!
Thanks!
