Reclamation not being properly recognised as completed

[John Snail]

I completed all the steps and got the completion messages, but I keep getting the quest fail confirmation every time I enter and then leave Omonporch. I had saved and quit in the middle of the quest, and left the high mecha alive. The golem keeps playing the quest music.

(Could you guys send back a fixed save? I want to keep playing as this character but don’t know if something’s secretly wrong with it.)

To clarify, by “left the high mecha alive” I mean I infiltrated it, shot the guy inside (which completed the step), and left.
