Kingdom Hearts II I'm short a plus?

Ok this is very strange... Please correct me if i'm wrong... You need 7 orichalcum + for Ultima Weapon, right? Well... Ive looked up how to get all 7: 1. finish 100 acre wood
2. collect one of every synthesizable item that isnt orichalcum + then
submit it to the moogle
3. A chest at the world that never was: brink of despair has it
4. finish atlantis
5. beat the goddess of destiny cup
6. A chest in space paranoids: central computer area has it
7. A chest at twilight town: sunset terrace has it

I did everything on that list, and only came out with 6.0.0
I mean everything to, I even went back to check! Now I havent gotten to lvl 9 moogle yet, but i'm asuming that I need 7 orichalcum + for Ultima Weapon, So my two questions are:

1: How could I be short one? I did everything!

2: Does Ultima Weapon need 6 orichalcum +, or 7?

 

Try looking around every world for a chest. you might findone along the way. There's a list of the number of chests that you find in Jiminy's Journal. Try looking in there.

 

So you have the Ultima recipe from the hallway to the Pod Room, right?

And you got the ones from:

-Central Computer Mesa (Space Paranoids)
-Sunset Terrace (Twilight Town)
-The Brink of Despair (TWTNW)
-Starry Hill (100 Acre Woods)
-finishing Atlantica
-beating the Goddess of Fate Cup (Olympus Coliseum)
-Obtain 45 different material types, obtain a total of 1000 materials, and obtained all material types.

You need all 7 AND the recipe...or just try to do it with the recipe and the 6 you have. I don't know. One of them will work. :xp:

 

Ah hah! I found it, It was in the world that never was, I thought they were talking about that chest right next to the moogle, but it was that hidden one in that ally... Thx guys!
