CRASH lost my lp bc of it

I lost lp to a bug that caused me to stay in loading screen without any indication that I was afk in the game. The green circle at the bottom right was still moving, my ping was fine and I even had music going that was on youtube. I didn't get a single bugsplat but a notification that basically stated, your game had been corrupted and when I got that notification the game was already over.

I somehow got this bug by loading into league of legends loading screen and waiting for 10 minutes.

Riot please fix this issue, Love Frost*[zombie-nunu-bummed]*

It did it again!!!! PLEASE, I need help, I played 3-4 then it got me stuck in loading screen.
