Sunken Pyramid quest broken??

[Myduditz]

I didn't use my Sparrow to go the the Sunken Pyramid, I was just exploring following the lamps Lights as a path. There is no arrow indicating where to go. I got to the Sunken Pyramid unchallenged. It is locked. I retried it twice and I have the same issue. After killing the big Moth like Savatun the door opens and then nothing... Am I missing something that need to be activated?

There are enemies and a pay load platform to "push."

I quit the game and came back to the same problem. I then went to the PS4 and tried it there and it worked.
