According to rules:
3.3.3. Disconnections and Player Compensation
c. If 3 or more people disconnect before or during a race with at least one from each team, the race does not count and the host must close the room.
Hence the first race does not count and the race should be replayed.
Please provide a picture of the first race.
Also, I recommend you to play the race next sunday 15 min before the next MKU war so there are high probabilities that both teams will be able to play it.
I am sorry for the outcome of this, but I always recommend to read rules before the beginning of the season,
Thanks
Kind regards,
Gumer
