[2022] Twitch items not claimable

If you have claimed your Twitch rewards from www.twitch.tv, they are redeemed automatically in game. There shouldn’t be anything you need to “claim” in New World. Housing décor are automatically available within your housing décor inventory in Decorate Mode, and gear skins can be found unlocked within the Skin Preview window (left-click on a piece of gear you’re wearing and select Change Skin from the contextual menu).
