I'm unsure if this is considered a bug, but it's possible for Animal Extermination [A] (CR01) to choose Svana's home (meaning Haelga's Bunkhouse). The problem is that there are nearly always NPCs in there and said NPCs may end up dead. In my case an ice wraith was inside along with Fastred, Bassianus Axius, and Swims-in-Deep-Water. Before I could intervene both Fastred and Bassianus were dead. Usually the game makes NPCs wait outside their home, but in this case it probably can't do this since the location contains a number of NPCs, similar to an inn. It kind of seems like this particular location should be exempted from being chosen.
