My nemesis draft Summoners icon allready got ruined in my SECOND game due to bugs :(

ive tolerated this bug until now

once in a blue moon (even before nemesis draft was introduced), though more common than I would like...if one of my friends hosts and I click accept it stays in the launcher screen and hear the music playing for the champion select , and then I cant select because im still in the main menu . im gonna end up with like 10 hour time waits if I even try to play nemesis....and now I lost my icon and ive only played 3 nemesis total :( that's hardly fair

edit: its roughly 1 in 10 games this happens
