Incorrect rating game result

[thynson]

This is a rating game contributed by my computer. its komi setting is 6.5 but the result of this game is draw(which I believe should be W+1.5). To my best knowledge of Go rules, draw should be impossible on non-integral komi games unless allowed by superko.

well,look at the Rules line:
Rules: {'ko': 'SIMPLE', 'tax': 'NONE', 'scoring': 'AREA', 'suicide': True, 'hasButton': True}
'hasButten' means the first player to pass would be rewarded by 0.5 point, which means the actual komi is 7 ,so the result is draw
