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

Action Reasoning:
To achieve the goal state, car_1 needs to be moved to curb_1. Since curb_2 is empty, we can temporarily move car_1 to curb_2, freeing curb_3 for car_3 to become clear and allowing future rearrangements.

New State Description:
Curb_0 contains car_0, clear. Curb_1 contains car_2, clear. Curb_2 contains car_1, clear. Curb_3 contains car_3, clear. Car_0 is parked and clear. Car_1 is parked and clear. Car_2 is parked and clear. Car_3 is parked and clear.
