Bug have to do with "JukeBox"
It's giving some kind of tnt render how I call it.

Steps to take to get this bug:

1 - Just place a "JukeBox" near a tree for EXAMPLE.
2 - Save the game because you think that "JukeBox" is placed well there.
3 - Start (Or restart) the world where you have placed the "JukeBox".
4 - Delete the "JukeBox" because you don't like the place of the "JukeBox" anymore.
5 - Start (Or restart) The world where you have placed the "JukeBox" again.
6 - If you look everything on the place where the "JukeBox" Have been placed is rendered to his normal state before you have created anything there. But on some how all the trees or cactus for example have been deleted and also the house or structure you have created have been deleted as well.

(This is been tested with complete "Vanilla Minecraft" with a "Fresh Update")
(Also been tested on my "PC" with Windows 7).
