Hello, I encountered this scoring system bug today.
During the scoring phase, both players made sure all dead stones were marked correctly. In the score preview, the right side was all white territory. But when we clicked “Accept,” the game went from white winning 40 plus to black winning by 20.5. Whites entire right side registers as neutral.
The Q9 stone is marked as capture. From the grave it turned 60+ white points into dust!
AdamR explained the problem in a similar report:
It’s been suggested that the scoring system should be replaced entirely.
In the meantime, I have a suggestion. The score preview should tell players what the final score is going to be before they click “Accept.” This could allow players a chance to “Cancel” scoring and play out the game to correct the territory. This should bypass the scoring bug.
Players should know what they are accepting. Maybe if losing players saw the score as they marked the dead stones they would just resign at the score preview window. This would be another the way to bypass the problem altogether. If players just resign, the bug can never occur.
