Can't use monk scalp of superior healing?

I haven't played my Prophecies monk in a while, but I recently got Factions and I took my monk over to Cantha and after I got to Kaineng Center I tried to swap out my scalp of minor healing to my scalp of superior healing and I could not. Does anyone have any idea why I'm not allowed to wear my superior scalp now?

I can't help you with the problem, but you might want to post it in the Bug section.

Is it your scalp- is it customized for that character? You can't trade scalps or any piece of armour with anyone else or another character on your account. I know this is obvious, but sometimes the obvious answer is the one.

Another possibility...I seem to remember that you can drag-and-drop the new armor from inventory onto the existing piece in the body model, but not the other way around. I don't see why it matters, but whatever. Just one of those things.

Well, I figured out the problem. Apparently, it was the foot armor with Superior healing instead of scalp. The weird thing is that I don't recall ever placing any superior runes on any piece of armor except the head piece armor. This goes for all my characters. So I'm not sure if somewhere along the line I put this on the foot and didn't remember or if there truly was a bug in the game and my superior rune was moved from scalp to foot.

I guess it's more likely that I just put it on foot and didn't remember it than a bug in the game, but I would almost swear on my life that I had the superior rune on the scalp.
