Accepting game invites Dodges Qs without warning

I recently Accepted a Game invite while in a lobby on accident, the client froze and said everyone had left the lobby, after a few moments it returns me to the main page of the Client. I go to Q up and I've got a Dodge Penalty.

If this inst a Bug then I must suggest that a Warning message be given to the Player. When in a Lobby accepting an invite should display a message asking the Player if they would like to join the game, letting the player also know that this action will cause him to dodge the Lobby and be penalized.
