Null points in the middle of the game

[DeepPurple]

Hello everyone, while i was in the middle of a Dominion game suddenly it stopped and the end info appeared with null points for me and the other player despite the fact that the game was far from being over. No provinces had been bought yet and only the Nobles were finished. Does anyone know why that happened ?
Thank you.
