Is it just me or what, sometimes when I'm playing the game goes black, it doesn't crash or anything, if you press ESC, you can hear the sound, move the mouse you can hear the sound, but the screen is all black, the rest of the computer works, I can alt tab it back to Aurora (as a matter of fact I'm writing this trying to "save" my battle which was at an end without having to close the game and open again, due to this bloody problem)

What the hell?
