Scoring error at Boston.

[GaryVoshol]

It has been reported that the sensors are very sensitive to balls going backward through the goal. It is not widely documented, but the score system is meant to work this way, based on rule <G16>:

<G16> BALL Return - HUMAN PLAYERS must place BALLS on the BALL RETURN using the TRIDENT. No other means are permitted for TEAMS to return BALLS to the FIELD. Violation: Two PENALTIES and YELLOW CARD.

If the ball goes backward through the sensor, even slightly, the score system automatically deducts two points as the penalty.
