Incorrect buttons don't fix themselves

[Alan Pope 🍺🐧🐱 🦄]

If you select a number incorrectly, perhaps putting a 1 at position 5,5 in a line where there is already a 1 placed at 5,1 , the second 1 you place (at 5,5) gets highlighted. This is great, but if you then fix the "other" 1 (at 5,1) the 1 at 5,5 stays highlighted until you tap it again.

I would expect that if you fix an error somewhere in a line/square, the other button in the line/square should autofix itself. The board should probably refresh-draw itself after each button press, to accomplish this simply.

In this example. On the line under the "G" of game. I had a 1 where the 6 is, and put a second 1 by accident where the highlighted 1 is now. I then corrected the 1 to a 6 (as you see the state now) and other other 1 stays dark, but should not, in my opinion.
