So, in the Survival Mode of Minecraft 1.7.2 (or 1.7.1) after playing for a while, the game would randomly crash leaving no Error Report whatsoever.

I expected to just play a simple game of Survival and make a large house to live in.

But, what actually happend was the window would dissapear randomly. I would check in the location of my minecraft application, and there would be no error report.

If you want to see this yourself, start Minecraft, then hit Singleplayer. Then, click "Create New World". Make sure you start in Survival Mode. Finally, start playing for a bit (about one ingame day), and the game will finally crash
