I am having the same issue partially. I have purchased every DLC for the game and I cannot make Wartorn fodder. In the knowledge list it shows me the icon that indicates it needs to be purchased/downloaded, even though I have purchased every DLC and made sure they are installed on my XBox. It won’t even let me learn it. Even stranger, when I played on a solo game, it did let me learn and make it. I am playing on two separate rented GPortal servers and I cannot learn the recipe on eiother one. I bouhg tit, I want it!
