ok here is the story of how I found that spawner and why it got blown up :p I made a nether portal in the ScoutArmy base (now Raided) went inside and found a nether fortress claimed by "CuddleFest". I found a way inside walked down a hallway and found a blaze spawner claimed by CuddleFest. I got by it safely without burning to death and went off to explore more on the fortress when I turned a corner and went down another hallway. Then in the chat I saw: ~Bambi - Once a Bambi, Always a Bambi. In front of me was a weird construction of cobblestone without any entrance of any kind. Being as curious as I am I blew a hole in the cobble just to see what was inside, and right after I lit the tnt I head a Wither Skeleton suffocating in a block, then the tnt exposed the spawner but did no harm to it, I msged Map and Claire that I found a Wither Spawner claimed by bambi and tped them to me, and map wanted to see if there were chests anywhere within he construction, I asked her to make sure to not destroy that spawner, but she blew it up by mistake anyways xD :p and there ya have it, that's my story :D
