I did not receive the League Brawl reward ( Castle Skin )  even after refresh and this is the third time I have not received the reward

Hi, ANGSTROM. Among the rewards for the League Brawl events, there is no Castle Skin. Seems like you've confused it with the League Fortress Skin which is given to those teams that are placed first in their tiers till the next winners will be announced.

So, this is not a bug.
