First, sorry for my bad English.

I'm a player at level 6 Pro, this afternoon I had a match at my league at 16:32 pm. When I was watching the match, the result was 5-0 for me (I won) (70th minute of the match). But suddenly there was an error an I was out of the game. (error from Nordeus). After 15 minutes, I loged in again and the result was 0-0???? I just have one point, he has one point.??? What happened??? This highlights of this game is blank.

Before this match I won 13/13 games of league while my opponent is 12th. Now i just have one point from this game? Give me an reason.
