This fortress was made with command blocks, after a world download some may not work. Please have command blocks enabled if you are to see some of the custom mobs. This item was made for players not to destroy the spawners from. This nether map also contains no other structures.
Suggested to use multiverse and import with /mvimport [name of file] nether -g CleanRoomGenerator
