Elaaden - Architect on Elaaden - Architect is stuck floating in the air

Had the same issue. What I did to fix it was fast travel to the foward station right in front of the quest, saved the game, swapped out 1 party member, ran over to where the architect was and then reloaded the saved that I had created. When I loaded it up I heard Drack say something about the fight and walked over the that area and it finally came down to fight me. Hope the helps/works for you.
