I looked around and did not find any info on this exact bug per say, so I am reporting it.

Hyperion Server/PS3/ATT-DSL
Character at the time of Glitch: Mister Gremlin

CRP level 35 LeveQuest in Gridania "Flintstone Flight".

The quest calls for 3 Walnut "Macuahimeh" to be turned in.
In crafting log/Market board I only find Walnut "Macuahuitl".

Upon purchasing 3 Macuahuitl from the Market Board and attempting to complete the quest. It removed 1/3 from my inventory, however on screen duty display shows 2/3 turned in. I still have 2 Macuahuitl in my inventory and it will not allow me to complete the Leve (it is a repeatable leve as well). I did get the full reward of 19,600xp and 488 gil for the attempt (which should have removed all 3 items from my inventory).

So to be clear, I bought 3 items needed for 1 attempt at a Leve, it removed 1 item from my players inventory, gave me the reward for what should have been a 3 item removal from my inventory. The progress now says I have turned in 2/3 (which I assume would be a 3 item+3 item due to the possible repeating) and I am unable to turn in the other 2 items or advance the Levequest to completion. As shown above the names of the inventory items do not match either. I took 4 screenshots on my ps3, but I have no idea where and if I should submit them.

I am hoping this is a known issue and will be fixed soon.
