As the title says, I started my third save a while ago (my first save is level 81 with over 650 hours playing time - second about level 50 or something with about 200 hours, I can't really remember) and I just came back to it to see what progress I have done with it (I haven't' played my third save in a while) and when I was checking my inventory I stumbled upon 2x Skeleton keys??????

Why is that? Does anybody know?

P.S. When I returned the Skeleton Key, one remained in my inventory and now I have a Skeleton Key to always use! Thank you, Bethesda!
