I just switched to the venthyr covenant. I am stuck in sinfall with a directive to "Complete the quest ‘A Calling in Service’ to continue the campaign.
No such quest exists. It appears from online discussion this is a known bug. I went from renown 38 to not being able to proress renown at all, or even access soulbinds or conduits. The game is unplayable. Is Blizzard going to address this, or are we all sh*t out of luck?
