Visual Glitch or misunderstood?

In game 5362 right now, there's an empty blue hexagon drawn in the lower left region of the board. I've got not idea what it's supposed to represent. Is it a bug or a feature?

It's a feature, which probably needs to be changed/improved :).
Like in Samurai, there is a colored border around the hexes to indicate last turn actions by each player. The void blue hexagon means that there was a Desert which has been moved away by the blue player, leaving an empty spot.

Riiiiight.

Definite agreement: there needs to be a better display of that. Perhaps text like "Desert -> -7,2"? Maybe just "desert moved"

Although that begs the question of how a human being can reliably figure out the hex coordinates. Maybe the (arduous) addition of a boarder of coordinate labeled hexes? My guess is that the answer to that is "ick" on both coding and interface levels.
