I went to go ride my horse in Funkytown, and discovered that someone stole my horse. There was also a saddle on the horse that is missing. They left a sign, too, saying that they stole him. :( My chickens are also all gone (that part is minor, though, and I can replace them myself). Finally, my neighbor's chicken coop was completely griefed. They aren't online as often as I am, so I feel like I should report that, too. 

My missing horse is at x= 160.33401 z= 3094.00374

The coop is at x=266.83755 z= 3102.82986

Thanks for your time. :)
