Never had this issue before where I get stuck at 0% in the loading screen, this was DURING my promos, so I lost those...
The team remaked.
I couldn't alt+tab, alt+f4, ANYTHING... not even task manager could save me
I'm just so %%%%ing sad this happened..
Riot PLEASE look into this.
I had an issue similar to this where when the game was over, I couldn't click to close the game, couldn't alt tab etc etc..
This just %%%%ing blows because I KNOW Riot won't look into this or even care, and I know this will happen to me again.
