Crash

Crashes are unexpected shut downs of the game. They are found when a player has a glitch in they're save or uses map editors to import certain blocks that do not exist in the game. Crashes will close the Minecraft window when they happen. This can corrupt save files and create bugs in the game.

Older Crashes
Crashes used to have an error report but that feature has been removed due to large amounts of mail inside Notch's Inbox.



How they can happen

 * Unknown block ids in-game
 * Sometimes opening a chest
 * Editing the save file without knowing what your doing

There are many other ways but have not been listed here, please provide us with some here
