Mordra missing?

[feasoron]

I've stopped Horace, reunited rowena and trent, but when I go to ask about the sacrifice Mordra is missing, so I can't finish the quest. Any ideas?

Have you searched outside her house? Sometimes she goes off for a walk near the giant mushrooms or into the cemetery.

I had a problem with Quenton missing after defeating Horrace. What I think happened was that I wanted to nap until around midnight, and I slept on one of the slabs in the tower where the ghosts go. It turns out that the slab I'd napped on was Quenton's, and he disappeared from the game. I had to reload from an earlier spot and go through the sequence again (I slept on my bedroll away from the tower).
