About to try this out then.
That happened to me, I just restarted and I also never got the spire to form when I first tried, I always had to start leave and then resume.Doesn't work for me. When I come back from sitting there for 2-3 minutes, I see the spire, but when I'm about to go to the door, the spire disappears.
Same thing for me.i tried it on hard and it works.
i waited on that spot for about 2 mins. the gate was not open so i went back to orbit.
then i loaded the hard mode again and i had that checkpoint before the templar.
i went all the way back to the first chest, but there was nothing.
