Solved Accidentally sold my Gem Bag. Is there any way to buy it back?

Unfortunately not @hdu914, if you already left that game or had multiple characters join it before it was gone from the games list. This is one of the reasons we recommend keeping lower quantities, no more than a few hundred gems per gem bag, as mentioned in the guide thread.

@TheDarkestHate, that's correct. Not all items sold accidentally to a NPC can be purchased back under the Misc tab, but in this case the bag would've showed up there since it was sold to Charsi and not Akara.
