After three days straight of playing the Beta there have been two consistent problems.
1. The client refuses to load after a game sometimes forcing me to force quit the client and reload.
2. The client will sometimes not allow me to invite a friend to play with arranged teams. It wont allow me to view the friends i can invite so i have to go to my friends list and manually invite them
