Just finished a comp game. In the post match it said it was processing but nothings in my career now and I did not receive the rr? Whats this about ?

I was in a standard Unrated game today and was in a duel with a Chamber, I hit him for **162hp** and as seen on the attached screenshot, he did not die from it. No healing could have been involved as all damage was dealt within 5-ish second...
