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

Action Reasoning:
To move towards achieving the goal state, car3, currently behind car0 on curb_3, should move to the now empty curb_1. This sets up car0 to move and positions car3 correctly spatially for the goal state.

New State Description:
Curb_0: Car_1 is parked on it and is clear.  Curb_1: Car_3 is now parked on it and is clear.  Curb_2: Car_2 is parked on it and is clear.  Curb_3: Car_0 is parked on it and is clear.  Car_3 is moved, making Curb_3 clear as car0 no longer has a car doubled parked behind it.

Action Chosen:
(move-car-to-curb car3 car0 curb_1)
