I think that support are more than likely to be right, and you made a mistake when you crafted your  BJORNS helmet.

I think I know how it happened.

When you craft the common items in the forge it always puts the highest available material in the slot , and you have to change it to a lower quality if thats what you want.

I believe it doesnt follow this pattern when you craft special items as it ought to do, because this is what the player is used to.

So this is a timely warning to everyone one else in future,

##check what has been added before you click craft##

I have to wonder why the programmers  choose to do this procedure differently  on this occasion,  and if it was a deliberate sleight of hand,  as there are other similar examples in the game which can lead the  unwary player into expensive mistakes.

I think I made a mistake here, I ought to have checked  properly before I posted.

I know I had trouble with things I had not showing as being available to craft  special items with , and  discovered that your  Hero couldnt be using them, and also had to physically add equipment, but I misremembered the rest and got it wrong .

It does seem to put the highest material that you have wherever a  material is needed,and you have to physically change it  to get lesser quality to show.
