Accepts game but screen is stuck at the accept or decline timer

In the new invasion game mode, when I accept the game the timer remains on the screen for a long period of time and I am unable to enter the game I accepted. Afterwards, when the timer finally leaves, I am returned to the lobby with a box saying that an "unexpected error occurred." I cannot even leave the lobby by clicking the x on the bottom afterwards and must log out order to leave. Anyone else?
