Sands of Inaros third part

[(PSN)Boiyan]

Hey guys 

 

I’d love some help. I’m trying to get Inaros and I need the last part to craft him. All I need to do is return to the tomb after killing the bursas. However after killing bursas I got no text or speech dialogue and when I load into the tomb mission I hear no dialogue either . I get to the vessel and pick it up and then literally nothing happens. No enemies no text no speech nothing. I’ve been stuck like this for a good hour or so and no idea how to progress. I’ve changed active status for mission and retried multiple times and with different frames . Help?
