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

Action Reasoning:
The robot should paint tile_1-4 black, as it is directly below the current position and matches the goal state color. This will bring us closer to achieving the goal state.

New State Description:
- Robot1 is on tile_0-4, holding the color black.- Tile_0-4 is occupied by Robot1.- Tile_1-3 is painted white and is no longer clear.- Tile_1-4 is painted black and is no longer clear.- Tiles tile_0-1, tile_0-2, tile_0-3, tile_0-5, tile_1-1, tile_1-2, and tile_1-5 remain clear and unpainted.- The colors white and black are available for switching.

Action Chosen:
paint-down(robot1, tile_1-4, tile_0-4, black)
