rito where is my orianna skin

Rewards take some time to roll out. They should be there before the 12th december, if I remember correctly.

Not all rewards are given at the same time, if it said you had been given them, it could be to do with this same issue that EUW and EUNE were having, which was posted about here. https://boards.euw.leagueoflegends.com/en/c/champions-gameplay-en/Y4Eqfgc0-euweune-end-of-season-rewards-processing-ongoing . Hope this helps.
