Request to cancel my winnings

Write a comment in the giveaway saying you need a reroll.
The creator can then ask staff to give the game to a new winner.

I think that the "awaiting feedback" winnings aren't shown on the profile. Or are they? I don't think so.

And I suppose, based on this

Clash of clans addon/

that it was dlc, and, you can enter dlc giveaways because it doesn't recognize owned status. Often. Not sure if always.
