Parent State ID: 7
State Depth: 5
Action Taken: put-down(c)
Action Reasoning: To reach the goal state, we need block `c` on the table supporting block `b`. Since block `c` is clear and on block `b`, I will put down block `c` to achieve the desired configuration for block `b` to be placed on top of block `c`.
State Description: Block `a` is on block `d` and clear. Block `b` is on the table and clear. Block `c` is on the table and clear. Block `d` is on the table, supporting block `a`. The hand is empty.
Action Path: ['unstack(d a)', 'put-down(d)', 'pick-up(a)', 'stack(a d)', 'put-down(c)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: The precondition for `put-down(c)` is not satisfied because the hand is not holding `c`.
