These fixes were rolled out last week for PC and this afternoon for Playstation and Xbox. Since this is a backend update, there should be no need for a patch download. These fixes will become active the next time you boot up the game.
Fixed the infinite loading for the advent calendar
Gave the advent missing rewards from last week as a sign-in reward for players that missed out on it due to the bug above
Fixed ‘Claim all Bögenhafen Cosmetics’ challenge not counting weapon skins bought through Lohner’s Emporium
