FFIV Adv - The Blacksmith is a cow! T_T

[Alexander]

I mean, I've taken the damn Adamantite and my Sword of Legend to him. He started to work. Well, I went down and it still isn't ready. I've left the house and re-entered it, and he still was working. I went to the overworld, and came back... and he is still doing the damn Excalibur. I've even went to Baron, defeated Odin, and came back! AND HE IS STILL SAYING "Hey, give me some time! Don't rush me!"

I remember clearly that I didn't have to do a thing to get my Excalibur in the SNES version. What have I done wrong? Or should I do something that I didn't do?

(By the storyline, I just edefeated Demon Wall and was backstabbed by Kain, and got my drill, did Yang's sidequest, etc etc)
