While I was playing the last Coney Island Mission and manage to kill the last target/boss, I was disconnected when playing the cinematic. Then after I logged in again, the task to eliminate the target didn't disappear, and the mission area still appear on the map. There was one player in my group and he froze, didn't move at all or reply to my chat. So I waited for 30 minutes, and nothing happened. Then I tried to log out and log in again. My team was gone and I had to restart the whole mission FROM the START.
