No joking or exaggerating, Diana just hit me so hard my game crashed

All I saw was Diana ulting to me, removing a giant portion of my health and then the game froze for like 5 seconds and then crashed with a bugsplat. I didn't even see myself die, but I can guess with quite good accuracy what happened. Luckily this was a normal game with friends and the game ended just a few tens of seconds later.
