hello! recently mojang released snapshot week 25. i will have the link lower in the the topic. but the main point is this awesomeness allowing people to switch worlds from creative to survival to adventure or vice versa. that means that you can replace lost blocks or make your self an ultimate palace to survive in. i practically spent all of this evening blowing up my stuff and burning down villages. i recommend that you download this and test it out. link: http://www.mojang.com/ enjoy.
