During my last game, my opponent (Facualma) left the game in voluntary manner just at the end of last end when it was 3pts up, but without hammer. Then I was enable to try to recover score, was credited of 2 points als lost game. So 2 learnings: 1) Facualma is a cheater, he deserves a demerit point. 2) Again and again and again. In this case when a player leaves a game (for whatever reason) he should loase the gam. I cannot understand why this issue is not fixed by moderators/developpers
