Ok t'is late or early which ever ye like to see it so forgive if I ain't extremely clear :p
Gaved my copy of the key to Krandor to Set to make sure I had the key to my house to Leilon on me (yes I saw after all this was done that there's a way to check which key is which :p) Open my door in Leilon, had the right key went in, spawned the key creator, made a copy of the key, gaved key to Set, he returned my copy of the key to the house in Krandor.
He went back out to try the copy, in the mean time I destroyed the creator and then went back out. His copy didn't work, tried mine it worked. We switched keys, I tried the one I gaved him, it worked, he tried mine it worked. So we exchanged key's again so I would have the original and he the copy, tried again and they both worked. By this time he was falling asleep on his keyboard so logged. I went to the house in Krandor to check something and couldn't get in.
My copy to the house in Krandor is no longer working :S
