the DLC isnt there. i dont see any items that comes with that DLC. :/
I guess you'd need to encounter a Lindwurm and craft a Lindwurm armor.
You could also unzip the game files and see whether the images are there.
dint think of that. but I already asked for refund.
my achievements also dont work, cant unlock any. and after reading the forums, seems like devs gave up on this game.
