CANT DO ANYTHING AFTER CHAMP SELECTED"

SO got into a game, and select our first champ; mine was vayne. The game went to the first stage where u fight the creeps. HOWEVER, the champ we selected wasnt there (and this happened to everyone in the game). The game continued and went to the battle stage where the time counts down. the enemy creeps arent moving nor is my champ.

this resulted in a loss of 4 points for everyone. We all thought ok maybe now that its round 2 we can buy a new champ we'd be ok.

nope.... put the new champ on the map (i put garen ..and its says there 2/2, tho 1 only shows). game commenced, nothing on the map moves... not the creep nor garen... time still counts down.

i chose to exit game for a possible restart. once i restarted client, it tried to bring me back into game instantly, but i got a critical error "create a crash dump"..etc. did so(dunno where to send that tbh) but now im just sitting at home page with me in game that wont let me escape or continue.....

tried again to reloggin just incase, this time there was a wait we're experiencing a large amount of logins. etc (waited 1 min)

what? this is the first time i got a bug like this, and it seems to be pretty shitty at that [zombie-brand-facepalm]

anyone else experience this? and know how to fix
