Fix the villager in bw5 and bw9. bw5) In bw5, it is possible to break the villager by breaking the glow stone underneath it. I suggest making this a different blocks such as wood planks to flow with the map. bw9) In bw9, it is possible to push the villager off the map by using tnt. I suggest making a hut out of sandstone to flow with the map.
Normal sandstone is breakable. I'd recommend using sandstone slabs to create the exact same effect, just unbreakable :3 And support <3
