Yes, because we all left the race.
What happens is at some point in the race no command is functioning for anyone. Nobody can boost, nobody can change push lvl, nobody can pit. Game acts like we all left the race and continues with whatever orders we had at that moment.
Isn't this the 'someone has an old version of the game' problem from, like, 6 monthd ago? Everyone is fine until the first pits and then it all goes to pot. One of the online players has a previous version, it will only happen when they are online, otherwise it's OK for everyone.
