Ward reroll reward [ CLIENT]

Ps: I am sorry, I posted in TFT first, I deleted it now. I did not see that I was in the wrong section when I made my post.

Hi,

Today I rerolled 3 wards. It showed me that I got "pumpkin cat ward" in exchange for the 3 others. But when I go to my collection, it shows that I still do not have it. Help? [sg-soraka]
