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

Action Reasoning:
Robot1 needs to paint the tile directly below it (tile_3-3) with the black color it is currently holding, as tile_3-3 should be painted white according to the goal state. Since Robot1 cannot paint this tile in the current sequence, we'll use change-color to switch to white, allowing the correct sequence in the next action.

New State Description:
- Robot1 is on tile_3-3, holding the color white.- Row 0: tile_0-1, tile_0-2, tile_0-3 are clear.- Row 1: tile_1-1, tile_1-2, tile_1-3 are clear.- Row 2: tile_2-1, tile_2-2, tile_2-3 are clear.- Row 3: tile_3-1 is painted white, tile_3-2 is painted black, tile_3-3 is occupied by robot1.- Available Colors: White and black are available for switching.

Action Chosen:
change-color(robot1, black, white)
