Not Bug Leaf Glitch from Zakum

I just finished a Zakum run where I dropped the Eye of Fire, and I watched my character pick up the leaf. But now The leaf does not show up in my inventory? Is this a known glitch or not?

 

The leaf isnt an item, it grants 5k NX to your account.

 

Oh, wow now I feel stupid. Gonna go real the Royals Guide again. But then what is the maple leaf equip?

 

you get it from gachapon.
