Sigil quest NPCs disappeared after patch

Quest was incomplete before the patch, completed it after the patch, went to turn it in, and all the NPCs were missing. They don’t come back if you enter a realm and exit the game / restart it.

Version 0.7.6

Have you unlocked the Arcanist yet? That’s a new prerequisite for them to appear.
