I would like to know this please Chrstina :), and if a patch can't be done. I have actually suggested a way of fixing this by simply allowing the v.s AI mode to be played offline. Since if this was added trophy hunters could earn this trophy by playing the game offline pre-patch.
Xbox One version probably never will be fixed by any patch for this boring as hell atcade medium class game » Dirt 4! Low fps made unplayable this arcade title, stage creator builds same boring tracks. And here Codemasters show how boring games they made... maybe only for British players? That's have a sense.
