You know, I didn't crash, But yesterday and a few days before, Whenever i tried to search, My game would go into Full R0 Mode and I'd disconnect down to like, 76% and back up, Repeatedly. I flushed my DNS and restarted my PC, Seemed to fix it for me.

As far as your concerns go, Run a File check, It'll take a few hours, But thats your best bet.
