I'm pretty sure the upcoming patch will fix it, but I'm not 100% on that. The full patch list is rumored to go up 2 hours after the patch goes up.
Anyways, for Sunday, 5pm, it'll be Cars this time. Not DLC based like I planned unless they put it all out at once. I plan on doing it for 2 hours, or until everyone leaves. The main focus will be Freeburn Challenges, not Time Challenges. Just make sure you have enough time to download the patch before playing. I've heard it's a pretty substantial update, upwards of 150mb.
Why focus on Freeburn Challenges?
Well...you unlock a car by doing 2 sets of Freeburn Challenges (Not Time Challenges), and I thought people would want help in making progress for that car.
