Hahahaha yea saw that a lot
But then it wasn't really a bug on the game engine's side. Apparently the game viewer is buggy and misinterprets the match data. Maybe the play by play would show something different.
There was once I actually beat my opponent by 1 point in game due to a buzzerbeater, but I lost the game when I checked the results. Somehow they managed to score a basket after the time ended to pull off the win. But that's actually the probem with the game viewer, not the box score.
