Guild Wars 2

I was crafting ascended armor and an ascended war horn so I crafted 6 lessor vision crystals and 1 vision crystal. So I had 6 lessors and 1 normal in my bank. I crafted 5 pieces of armor then I was going to craft the war horn. When I tried to crafted the war horn it showed I was missing the 1 vision crystal, then I noticed I still had 2 lessor vision crystals instead of just 1. So if you craft ascended armor when you have a normal vision crystal in your bank the game can use that one instead of the lessor. Can a dev please respond if I can get my normal vision crystal back so way?
Thanks

The chest piece requires a vision crystal, not a lesser vision crystal.

Indeed. As the above poster said, the chest uses a regular vision crystal.

Therefore you needed 4 lesser and 2 normal.

it’s a curve ball, but a full set of ascended armor requires 5 lesser and 1 regular vision crystal.
