I had recently given my Dawnbreaker to Uthgerd and somehow her inventory got wiped. Is there an easy solution to this problem? Is there a way to spawn it back in using commands? That was a really cool looking sword and I was going to hang on my wall in my house.

I recommend you just spawn it back in with commands. It might feel cheap doing it, but keep in mind you've actually worked for it by doing the quest and it was then wiped with a bug.

Do you know the command to do that?

I don't have access to Skyrim at the moment, so not sure if this will work. Try typing "help dawnbreaker" in the console to get dawnbreaker's ID, then type "player.additem 1".

That worked, Thanks!
