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

Action Reasoning:
To move towards the goal state, we need to move car_3 to curb_3. All vehicles are clear and curb_3 is currently incorrectly occupied by car_1. We should move car_1 to curb_1, which contains car_2. First, move car_1 from curb_3 to double park behind car_0 on curb_0 to free curb_3 for car_3.

New State Description:
Curb_0 now has car_0 parked with car_1 double parked behind it; car_0 is not clear, car_1 is clear. Curb_1 retains car_2, clear. Curb_2 retains car_3, clear. Curb_3 is now empty, clear. Car_0 is parked, not clear. Car_1 is double parked, clear. Car_2 is parked, clear. Car_3 is parked, clear.

Action Chosen:
