Very early into my playthrough after getting to England I got the Vegvisir Scheme (Front) since getting this whenever I go to the tattoo artist instead of unlocking the tattoo I get the Galloglach Armor in my inventory. I've tried reloading saves, getting the armor first, buying tattoos, exiting the game and nothing seems to work. If I get the armor first it duplicates in my inventory when I talk to Svend.
