Repair Crash counts as lose?

Hi, today, this happened, we started a game, but while it was loading, the launcher went complete ape and started "repairing" some stuff, downloading, taking ages, my team called a remake and I lost LP....

Why did it happen? Any way to not make this happen in the future? I can't be losing LP just like that

What is funny, when it finished it tried to connect me back, but then a message popped out "The game is no longer running, feel free to play a new game"
