Okay thanks, that explains it since I dueled him.
Really bothers me when I have a key in my inventory I havent used then I dont play for a couple days and forget what it was to haha... I have one now and no clue what it goes to so I did not want another one...
Yeah kind of bugs me when there is a locked door I can't get into either I feel like it should just say "you can never open this door" or be non-interactable or something
Thanks for the response! Amazingly could not find any info on this on the net at all...
