It seems bizarre that in the Beta of Alhambra your own Alhambra is surrounded by yellow 'tiles' that are not actually tiles. Why?
These 'non-tiles' don't mean anything really (other than showing where you could potentially place a tile - but even then they don't help because impossible placement positions (like outside walls) show up yellow).
So my proposal is that in your own Alhambra the display should not shown extra yellow 'tiles' where there are not placed tiles. Instead your own Alhambra should show just like how the other player's Alhambra show up i.e. without the surrounding yellow 'non-tiles'.
