So I hire a bard. Next time I visit the house I have him play a song. He plays one song then wanders off. Next time I return to the house a dragon attacks the house and the bard is missing afterwards. I looked around all over afterwards and there was no corpse of the bard. There is no option to replace the missing bard either.

Is your house fully built?

I had a problem with the bard disappearing when I only had the first stage house. As soon as I upgraded the house to have the great hall the bard reappeared.

if its the bard in the falkreath location
he attacks enemies so iys possible he is dead

lost two horses so far but no bodies
just the option to replace them

If he is dead then it should have given you an inheritance letter right? Seems like eveyr NPC that dies in town I get one from the courrier. With both dragon and vampire attacks it becomes quite the common occurence.

Yes, it was the Falkwreath location. Yes, the manor is fully built, even everything but like two trophies inside, damn toothless sabre cats.
