Nar Shaddaa. Heroic mission in the spaceport. I have completed everything in the mission except the last part when you open the door to fight the boss during the event I went back to the medical droid to repair my gear then after when I would charge it to the door I could not get it in could not open the door the control button was smashed and the door was red marked. So now I am NOT able to complete that mission is this a game bug or am I missing something
