I was playing Minecraft on a multiplayer server, when the decides to just randomly exit out on me. This happened to me while I was playing in game. I was not paused, and I didn't hit "exit game" or any other menu button.

I didn't expect the game to randomly exit on me.

What happened was that I was just digging under my house and the game just quits itself. It exits the window so I have to open Minecraft. I was in multiplayer so I did not lose progress.

I don't know how to reproduce this bug. It happened so randomly.

Here is the report:
