@ beta testers: There's a bug in multiplayer races where backmarkers are triggering the checkered flag although they shouldn't be able to do so. This happened in the ACM grid 2 race last monday. Check this video at 1:08:20; when the guy in last place drives across the finish line, he is being shown the checkered flag and the timer for everyone else starts counting down already.
These are my logs, it happened in the second race. For the server logs, you'd probably have to ask the eSports team.
