I'm unable to feed the Palomino horse on my Imperial Dragonknight. Even though the horse shows as hungry in the menu, when I go to feed him, all the options for food are in red as if he's just been fed. I was able to feed my Imperial horse on my Breton Sorcerer just fine. I've never had any problems in switching from one character to another to feed their mounts. Both characters have only one horse. This is the first time I've seen this particular bug. I did try /redoadui and exiting the game, closing out the launcher and re-starting. Neither worked.
