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

Action Reasoning:
The next best action is to move robot1 to the right onto tile_1-5, which is clear, to position it correctly above tile_2-5. We need to complete the pattern by painting tile_1-5 with white, and this move aligns robot1 for that purpose.

- Robot1 is now on tile_1-5, holding the color black.- Tile_0-1 is clear.- Tile_0-2 is clear.- Tile_0-3 is clear.- Tile_0-4 is clear.- Tile_0-5 is clear.- Tile_1-1 is clear.- Tile_1-2 is painted black and is no longer clear.- Tile_1-3 is clear.- Tile_1-4 is clear.- Tile_1-5 is occupied by robot1 holding color black.- Tile_2-1 is painted black and is no longer clear.- Tile_2-2 is painted white and is no longer clear.- Tile_2-3 is painted black and is no longer clear.- Tile_2-4 is painted white and is no longer clear.- Tile_2-5 is painted black and is no longer clear.- Color white is available for switching.- Color black is available for switching.
