Couple of options... 1 is did you use the intercom once you went to the space. If the answer is yes and you are still stuck you can use the Emergency Fleet Ability to go to the fleet and then try again. I got stuck on the ship because I died and it put me on the wrong side of the wall and i couldn't go anywhere. I used the Fleet Pass and went back and finished it just fine

I'm level 31 (Shield tech tree) and was wondering if people are using him or if your sticking with Mako. Does his hard hitting attacks make up for no heals? I've used him in groups with a healing character and it's great but I'm worried about higher level mobs without him when solo.
