Not Marked As A Leaver?

Not that I want to be marked as a leaver. I don't leave games, period. The only time I have ever willfully left a game was several years ago when my son started vomiting out of the blue. But, for some reason, my computer basically exploded at the start of my last game. I had initially connected, so they couldn't remake. I don't know why, but it says it was a defeat in my match history, and my icon isn't marked out as a leaver.
