User blog comment:AutoBlood/Another White Stag?/@comment-1992639-20130103131258

Stuff like this happens with patches, if it is the Hircine white stag. I suddenly had Shadowmere standing outside the DB lair near Falkreath, while I actually KILLED the DB. Patching makes your games go funny sometimes. Some long dead NPC's came alive again also in the clean-up cell where corpses go for preservation in case the game needs them instead of deleting them outright.
