Image below of my AA window on 90 Necro Gold account. It won't let me purchase the next rank in Forage even though I meet all the requirements and have enough AA. There are several others grayed out that I want to purchase, most of which show an expansion I don't have, so that would be understandable. But I used Forage as an example because it's not tied to any expansion and still won't let me purchase. Is there something I'm just not understanding?
