While me and another one of my factions member were raiding we came across an illegal base. The base design was setup so if you blew up the top blocks water would fall down covering there spawners. I feel like we deserve the spawners due to the fact it was an illegal base defense as well as it was impossible for use to creeper egg. The Pictures were from single player due to the fact I world downloaded the base before hand. But I will also provide pictures of the base after we raided it.
