Legendary Chest Disappear

I started playing the competitive mode of heroes of the storm and when I was at 32 wins (if I remember correctly), one of the games my Internet connection was disconnected right on the scores screen (after winning the game) and it count as victory only on my profile and it does not appear in the quest chain. When I reached 35 victories, my profile already said 36 and they finally didn’t give me the legendary chest.
