Hate to break this potential bad news, but it appears that the '69 Charger endurance race at Indy is no longer paying out after the 2.0 Supercar update. I've tried both on- and off-line, logged into and out of GameCenter, and can't get beyond ~20 miles. The bots are faster, hold different lines (e.g. thru the straights,) and I simply can't get the bots to spawn.
Can anyone else please confirm?
