maybe a silly question : sometimes, in online races, there is a strange behaviour. cars in front of me go off the track because of an accident/a mistake and i pass them. but all over sudden, they are in front of me again without passing me just as they were fallen from the sky and look like ghostcars for a short time. that is really annoying. is this a bug? do people cheat somehow? or is there another reason? has anybody noticed that issue, too? thanks.
