Attempt Number: 3
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To progress towards the goal state, we need car2 to be in curb_2, and curb_1 is currently free. Thus, moving car2 from behind car0 (curb_0) to the empty curb_1 will clear curb_0, allowing specific re-arrangement necessary for goal achievement. Ensure action uniqueness to avoid past errors.

New State Description:
Curb_0: Car_0 parked, clear. Curb_1: Car_2 parked, clear. Curb_2: Car_1 parked, clear. Curb_3: Car_3 parked, clear. Cars: Car_0 clear, car_2 clear, car_1 clear, car_3 clear.

Action Chosen:
(move-car-to-curb car_2 car_0 curb_1)
