Yes, the bug was fixed on Friday. The server damage is 12700.
There is a UI issue, though. After you restart the game, the Maximum AP Shell Damage information switches back to 11500. You need to play a battle to see again the correct damage on the interface. The UI problem doesn't influence battle performance, and it will be fixed with 0.10.9.
