The following quest seems to be missing:
It's one of the non-clan related vampire quests. It's supposed to be given after talking with Raven Omayn when the player is a vampire. But the topic just doesn't show up. It could have something to do with Raven's location, she's supposed to be in the main chamber for the mouth but for some reason she & most of the other mouths end up in the little temple in the basement by just before the hermitage. Raven's other quests work fine from there though.
