Client Crash [CLIENT]

For some unknown reason, my client crashes about 15 minutes after I've logged in. There doesn't seem to be any other problem, and there are no crash logs as far as I am aware.

I played a quick bot game, and sure enough, the client didn't load upon completion of the game. For whatever reason, the client just shuts down after about ten to fifteen minutes.

I've tried finding crash logs in the LOGS folder, but there are none. I've checked every log from throughout today, and there is nothing out of the ordinary. Also, I even turned off my firewall temporarily between crashes, to see if it was the firewall shutting down the client. The client still proceeded to crash, so it isn't the firewall.

Running Windows x64

How to reproduce bug: No idea. It just randomly decides to crash about ten-fifteen minutes after logging in and just sitting on the home screen. I logged in, and left my computer alone for a bit, watching the GD chat. After eleven and a half minutes, it crashed.
