Hello Sermnik. Due to the holidays, there may be some delay before I can get someone to look into this for you. I’ll let you know when we’ve got some news.
In the meantime, I’d like to share some details about the skins themselves, because it can be confusing in that they are a little different than other skins. These skins, each called ‘Champion of Ubersreik,’ are only available to the first careers of every hero (Mercenary, Ranger Veteran, Waystalker, Witch Hunter Captain and Battle Wizard). When used, no selected cosmetic headgear will be shown with these skins, as they have their own headwear that cannot be swapped out. Hopefully you’ll find this information useful once you find the skins in your inventory.
