A minecraft challenge that builds upon BOb 1.
You get a minecraft world-save that's been corrupted. The flag is found in the same place as in BOb 1 but since you can't go into the world via the game you'll have to open the world save in NBTExplorer or a similar tool. Through NBTExplorer you can find the flag as long as you know the location in game (which you'll find if you solved BOb 1).
