I'm trying to solve a very specific issue and I'm hoping MooseEdit can help me...I looted and sold Sam's Collar not knowing I would eventually need it for a quest. I have checked every NPC I can, and none have it, so I'm assuming I sold it to somebody who is no longer available to interact with.

I'd like to add that one item to my inventory...how do I go about doing so? I looked through the list of items several times, and I didn't see it anywhere.
