Eru still won’t move to open the entrance to the next area in the Madman, Crowned main story quest. It has been this way since VoH released. This prevents access to Kurast Undercity, rune and mythic crafting, and half of Nahantu’s content.
I am sure that you have your top minds trying to figure out how to make him move for all players. However, an easy bypass fix that would allow players to continue progression is to change the trigger that opens the door from Eru’s position to when he completes his dialog instead. I’m sure that you’ll want to keep working on trying to make him move, but please, at least until then, change the trigger! Because honestly, I don’t think that it really matters where he is as long as I can move past this quest and access the rest of the expansion and content that has been unavailable for a whole season plus!
