So I had a purple staff equipped as my main weapon, but have been only using my backup weapon and never used my main one the entire time it was equiped. I eventually got a better staff to equip in my first slot, so I did and then went to dump all my purple items in the guild store. After I did that I went to go to a merchant to sell my purple staff assuming it was still there, but it wasn't in my inventory. I went back to the guild store to double check and sure enough there it is listed as an item for sale. Did this happen because it was never used, or was there something I'm missing with the rules to bound items? Also it could be a possible glitch since I had two exact copies of the staff, one bound and one not, which is probably how I came to sell it in the guild store without realizing it was my bound weapon.
