I'm not 100% sure if this is a bug or working as designed, but I have yet to see a zombie or skeleton with armor on in the BTU. There used to be plenty in the old Xbox version and based on the Wiki there should be armor capable Skeletons and Zombies in the BTU, but I can't find them. Is the change much much lower? Also, skeletons don't seem to drop enchanted bows anymore either. Working as designed or a bug?
