I am on the main story quest “To Walk a Different Path” where I am supposed to meet Neyrelle at the Horadric Vault, except I am getting an error in the quest saying “Quest progression is blocked due to party members not on the same step”… except I am not in a party, nor have I been since the expac started. I have mercs, so I tried dismissing them and restarting the game, but the story is still showing as blocked, so I am stuck atm and can’t continue the story.
If a restart doesn’t solve it, Google how to “restore licenses” on your Playstation. You just need to restore Diablo 4, not the entire SSD.
Now it should work again. I had the same trouble and that solved it for me.
