I was soloing the Alderaan Star Fortress but shortly after destroying the three terminal things in the reactor room I fell off a ledge and found the way back was blocked by an impassable door. There seems to be no way to get back, and I'm not sure if I'm missing something, it's bugged, or the designers are just sadists. If anyone knows what's up here I'd appreciate the help, because I'd really rather not have to start from the beginning because of something this asinine.
