Two problem with the horses -Speed/Armor-

[Ruhellex]

1. When ever you pick up a horse then place it. Its speed will double. If you keep picking it up and placeing it, you can get a horse that can break the sound barrier.
2. Any horse armor placed on the horse will disappear when you place it along with the saddle.
