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

Action Reasoning:
The robot is currently on tile_1-2 holding white. To achieve the goal state, it should paint tile_2-2 white. Painting down aligns with the goal, and since tile_2-2 is clear, this action is valid.

New State Description:
Tile tile_2-2 is now painted white and is no longer clear. Robot1 remains on tile_1-2, holding the color white. Tile_0-1, tile_0-3, tile_1-1, tile_1-3, tile_2-1, and tile_2-3 remain clear. The available colors for switching are still white and black.

Action Chosen:
paint-down(robot1, tile_2-2, tile_1-2, white)
