Some drivers liked it not having overlapping rides ("red rides") booked for them, and some did not.
So, we decided to put the overlapping rides back for now, until the time we add a special setting allowing you to specify if you want the overlapping rides, or not.
That said, what we DID NOT! rollback is reserving your Ride Credits for booking the overlapping rides: so now the Ride Credits are being reserved only for booking the rides, which DO NOT overlap each other.
Stay tuned for the update regarding the setting mentioned above.
