The Circuit of Ashbrook in class A, in rally not save the times. Is the third race in rally events.
Did you perhaps previously set a time in the Bone Shaker? If so, those times were removed from the leaderboard but are still taken into account, so unless you go faster than your old time, your new time won’t register. If it isn’t that then I dunno.
That must be it, I certainly spent time with Bone Shaker. I think that if the car and time were removed from the track, they should reset my times.
I recently got myself back on a leaderboard where I’d set a Bone Shaker time by using the Atomic Punk, so you might be able to beat your hidden old time with that.
