[A matter of Import bug]

Durring the quest a matter of import i somehow managed to lock the quest out of finishing. I delivered the scientist to the workshop and she gave me the diving helmet, i then went straight to the underwater ruins and i think doing that caused the fleet master not to be able to talk to be. I cant turn in the quest and thus cant finish the rauatai questline. please if anyones found a work around i really want to continue the questline
