Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since car_0 is double parked behind car_3 and can be moved, moving car_0 to the empty curb_1 will free curb_3 and get us closer to the goal state layout where car_0 is required at curb_0.

New State Description:
Curb_0: car_2 is parked and clear. Curb_1: car_0 is parked and clear. Curb_2: car_1 is parked and clear. Curb_3: car_3 is parked and clear. Car_2: Parked at curb_0 and clear. Car_1: Parked at curb_2 and clear. Car_0: Parked at curb_1 and clear. Car_3: Parked at curb_3 and clear.
