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

did you craft ascended armor chest piece, as this requires a normal vision crystal not the lesser one, this would explain what you had left over.
