How about turning the saddle into a wagon (not sure if that's how toy would do it), so it could be a horse and wagon with extra inventory. Just a thought. There's not a lot in the game for those of us who want to keep things in the medieval-ish era.
I now have the icon for the bag in the bottom right of the screen. It is currently red and says 'open', the bag is not, however, open and accessible, and pressing the B button doesn't do anything. Am I supposed to craft an actual bag? if so, then from which crafting station.
