Attempt Number: 2
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since fast0 is full and at n5, we need to offload passengers to align with the goal state. The best immediate action is for p3 to leave fast0 at n5 since their destination is n5. This clears space in fast0 and brings us closer to the goal state.

New State Description:
- fast0: At floor 5 (n5), 1/2 passengers (carrying p4).- fast1: At floor 0 (n0), 0/2 passengers.- slow0-0: At floor 2 (n2), 0/1 passengers.- p0: On floor 2 (n2).- p1: On floor 1 (n1).- p2: On floor 5 (n5).- p3: On floor 5 (n5).- p4: Onboard fast0 (at n5).- p5: On floor 0 (n0).- p6: On floor 2 (n2).

Action Chosen:
(leave p3 fast0 n5 2 1)
