Parent State ID: 10
State Depth: 5
Action Taken: (board p2 fast1 n4 n0 n1)
Action Reasoning: The next action in the plan is to board passenger p2 onto fast1 at floor n4. This aligns with the plan and moves us closer to the goal state by starting to transport p2 to their destination.
State Description: - fast0: At floor n0, 0/2 passengers.- fast1: At floor n4, 1/2 passengers (p2 on board).- slow0-0: At floor n0, 0/1 passengers.- slow1-0: At floor n3, 0/1 passengers.- p0: On floor n0.- p1: On floor n1.- p2: On board fast1.- p3: On floor n4.- p4: On floor n1.- p5: On floor n3.
Action Path: ['(board p0 slow0-0 n1 n0 n1)', '(move-down-slow slow0-0 n1 n0)', '(leave p0 slow0-0 n0 n1 n0)', '(move-up-fast fast1 n3 n4)', '(board p2 fast1 n4 n0 n1)']

INACTIVE REASON: action path invalid: The action `(board p2 fast1 n4 n0 n1)` is invalid because the precondition that `p2` must be on floor `n4` is not met; `p2` is already on board `fast1`. The current state's natural language description and visualization incorrectly show `p2` on board `fast1`, which is inconsistent with the action requirements.
