The workaround is long resting at Mountain Pass. You miss the tiefling party. Hope they fix it soon, but almost two weeks later it's still bugged.

There was a reddit thread from 4 months ago that had a similar problem, so it could have been bugged for awhile. I wouldn't count on it to be fixed immediately unless it gets to be a popular issue, so use the workaround if you're itching to play.
