Backpack Glitching

Toseno

On January 26, server 88,  I went into my backback to sell some Skill Scrolls and Bikini's and it allowed me to as usual, but when I sold the Bikini's it replaced the item and farced me to sell the "Aizen Couponx5" you recieved from Visored Revenge. I was wondering if you could give me the "Aizen Couponx5" back for the 10,000 silver I recieved from selling them. It would be greatly appreciated.
