Recently I bought the Large Delivery Wagon, but I already owned the Medium one. Now, both wagons appear for selection on Wilderness Outfitters menu, but for some weird reason i'm not being able to select the Medium one. I just bought the Large Wagon because it was on sale, but i have no interest in use it, i prefer to use the Medium one. i've been able to change most camp items on Wilderness Outfitters menu, but the wagons are no working, How do i change the Delivery Wagon?
