Read the whole thread but not seen this mentioned. If you put in a nonsense word of random letters and hammer the fire button, you can see the letters turn Orange or Green as it flashes, so the turn is not counted so you can find the letters and where the letters go. So it's not too difficult to get the solution in one step... One assumes it's checking the letters first, changing them, checking if it is valid and reseting it if it is not.
