NPC's on Ogrim's Hammer

Hey, is there any fix or workaround to get Ebon Blade quest chain from Koltira Deathweaver on Ogrim's Hammer?

I found 10 Dismissed bug reports about this and met 5 other players with same problem in 15 mins being there. All had the same problem as me - NPC's are just falling trough ship on the ground and can not be interacted with.

Some of those bug reports were 1 year old and I cant believe that no one could get to QM for a year, so there must be a way.

Same problem for me, can't find any way around it.
