Now whenever I receive an object as part of the rewards of an adventure, and I am offered the choice to store, place, or sell, I always sell it. I dont need more stuff in my inventory.
Im not sure they will ever give us the option to sell things in inventory. I have been playing this game for several years and I have seen hundreds of people ask for this function.
Ive actually never seen them give anything that anyone has ever requested here on the forums.
