9ds Make Scoring Mistake!

I just saw this match up between aggressive [9d] and MilanMilan [9d]. They are, respectively, Kwan Haekwang Korean amateur 7-dan and Peter Liu? Chinese professional 2-dan.

For the most part this game is confusing, it was blitz and had fights all over the board. Black made what should have been the losing move at 245 (Q9). I think he did not realize that 246 (E13) by White captured those 4 stones, he probably did not notice they were in atari.

However, it doesn't matter! Aggressive forgets to click some stones dead in the center and lost the game by 8.5! A quick count reveals that White should have won by 0.5! Be careful in scoring your games!
