Game froze 50 minutes in, could type, open store- but nothing else.

so 431 farm as ryze 50 minutes in one fight decides the game etc etc

I try to screenshot cs (lul ik, not impressive)

I suddenly can;t move. I get nuked, we lose the game.

I'm pretty fucking pissed- and i JUST upgraded to the new client.

Pretty SERIOUS BUG if you ask me??
