Weird bugsplat + match not in history + corrupted files?

All this just happened right now. I played a game, and just before the Nexus falls down, boom, bugsplat. I check history: the match isn't recorded (although it is on internet). The client closes, restart, and says it found corrupted files. https://s4.postimg.org/n5jchc4t9/image.png Is it a demon trying to possess me?
