Hey! I was recently messing around with some cheats on my Xbox, and while messing about destroying Blackwater, spawned in a racehorse using the "Run! Run! Run!" cheat. Last time I did that I got a Thoroughbred, and it seemed apt since my horse had buggered off and I was surrounded. However, what spawned was something rather different. Studying it showed it was a Blanket Appaloosa, which is already strange since they're classed as "work" horses, not race horses. Nonetheless, the really weird thing was the horse's coat. It looks almost zombie-like, with a dreadlocked mane and tail, and patches of hairless, almost green skin. It seems to act as any other horse, in the sense of building up bonding levels and being stabled: the stablehand didn't seem to have anything unique to say about the horse. Has anyone else encountered this at all, or have any idea what it might be in relation to?? I've encountered "zombie" humans in the game, so perhaps it's something to do with that? Or it may be something completely different!
