Bug Splats yet again

So a few days back I had a 5 game queue increase due to "leaving too many games" via bug splats. So after screwing with my settings I did like 10 bot games, 5 to clear it, and a few more to see if I'd bug splat anymore. Had no problems in any of them. So I did about 10 pvp games, have 0 problems. Do a ranked game with Kha'Zix and get a bug splat on the loading screen. I got in just after minions spawned thankfully, but I dunno why it bug splats. Has anyone else had this problem? I have determined I can't play Vladimir but I found that out a few weeks ago. But other than that I dunno why the game randomly crashes and it's really starting to piss me off to no end, because I cannot find a pattern for it, other than I almost always crash when I play Vladimir.
