Ranked Bugsplat and invisible champions

[Crash/Client]

Well, I've been playing league for about a year and a half and ran into many problems, but never actually came on boards to explain it. This time i seem to have been cursed by something because all of these problems came up at basically one time today. I launched league this morning and the client was supposed to patch. It stopped patching after about 10 minutes and gave me "error 004" and asks me o restart browser to try and patch again. I restarted it, but the problem persisted 3 different times.

I finally got the patch to work by spending an hour waiting for the full repair. I started a ranked game soon after, so why the hell did i get a bugsplat right after champion select. [zombie-brand-mindblown] Not during, not before, but after the champion select has ended and we're about to get into the match, i get a "Possible Data Corruption Detected" causing me to lose lp, derank and get on leaverbuster all while it's attempting to repair these corrupted files that should've been repaired during the "initiate full repair" sequence. If you thought this was the end, huehuehue.

I felt pissed so i went outside for a few hours and came back. Started another ranked game and waited 20 minutes for my 1st of 5 leaverbuster to be over. We chose all of our bans, but when it came time to choose our champions(i chose who was taken by an opponent just before i could get to her) my champion select screen went blank. The enemy's and my team's champs were visible, but none of my champios were visible or clickable for me to choose and it kicked me out of the room, putting me on a 30 minute queue dodge on top of the 20 minute leaverbuster. As of now i have it on a full repair for the 3rd time today. I HAVE TO WAIT AN HOUR TO PLAY THE GAME AND NONE OF THIS SHIT IS MY FAULT. I just want an explanation of how all of this shit can come about when i allowed my client to repair 3 different times today.
