[Seasons] Victory is not counted

Hello,

A recurring problem that significantly detracts from the enjoyment of playing Seasons: 

When your opponent leaves the game while you are leading the score, many times the game is not counted.

I even find myself playing in the hope that my opponent will stay, which is annoying.
