Has anyone experienced this bug?

I happened to be playing a ranked multiplayer race. During the qualifying session everything normal, I get 10th position, I'm not the best and I've never been on the podium or won any online races.

Suddenly, after the loading screen during the start time, it says I'm in the second lap, while the rest of the players are in the first lap... During the whole race I have been blue flagged and beating the 2nd by 1 lap as I said.

Obviously I won the race, but unfairly as the others started on the first lap, I don't know why I started on the 2nd lap... I didn't even have to start, I came straight out on the main straight at full speed like when you start as "fast lap" in free practice or qualifying.

It was quite a strange bug, in fact a lot of people left the race suddenly. We started with 18 people and ended up with 10. I hope I don't get banned, because it looks like I used some kind of cheat and I didn't do it.
