So, just got Hearthfire today and became a Thane of Falkreath as well as purchasing Lakeview Manor. I spent the better part of 2 hours going around and collecting the necessary components to build the house all in one go. Upon fast-traveling to my house, there was a Blood Dragon waiting for me! I quickly killed it, and noticed that my appointed Thane from Falkreath was patrolling around my house (This is not my companion, Mjoll the Huntress is). I talked to her because at first I didn't know that it was my Thane. I noticed the option to make her a Steward, and so I did. After entering my house to use the workbench, I noticed that Mjoll had not gone in with me. Upon leaving my house I noticed that she was not outside either. I fast-traveled to Riften and she was not waiting for me inside Honeyside, only Iona was.
So, I guess my question is.. Where did Mjoll go? Did I lose her forever due to this Blood Dragon? She can't die because she is an essential character, so where in the world of Skyrim could she have gone? I fast-traveled from Riverwood when I encountered this bug. She is not there waiting for me either.
Any help would be appreciated, because I did not save prior to doing my last 2 quests to become Thane or any of the collecting I did for my house, so I don't want to have to load to such an old file! Thanks!
