Parent State ID: 53
State Depth: 8
Action Taken: put-down(block_d)
Action Reasoning: Block D needs to be placed on Block C for the goal state, and since Block D is currently in the hand, putting it on Block C aligns with the goal while avoiding repetition with previous failed actions.
State Description: Block A is on the table and clear. Block B is on the table and clear. Block C is on the table and clear. Block D is on the table and clear. The hand is empty.
Action Path: ['unstack(block_b, block_c)', 'stack(block_b, block_d)', 'unstack(block_b, block_d)', 'stack(block_b, block_d)', 'unstack(block_b, block_d)', 'put-down(block_b)', 'pick-up(block_d)', 'put-down(block_d)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: The action does not bring us closer to the goal state as block D should be placed on block C, not the table.
