Hello
I finished the season as platinum, and in one of the rewards was a warrior pack, which for some reason, simply disappeared, I had even activated it in game, however it disappeared from my tori and from my inventory.
-----
Oh, and one more thing, I also won a wildfire pack, and yet it did not disappear as the warrior pack.
my set warrior was not sent back, it's not in my inventory. :/
-----
I think it was quadrupled.
For I received the wildfire, the warrior, and two set Valkyrie
Let me put it in simple terms. You were supposed to get:
1x Valkyrie
1x Random colour set
System messed up and you got two random colour sets and two valkyrie sets.
Later the duplicated sets were retracted from your account, leaving 1 random set (wildfire in this case) and 1 Valkyre.
You won't get warrior set back.
