Its seems that a dwarf named YANDERE is selling red gem (from the card game quest) at 10kk... OK, normal scam. NO!!!!! I SEE HER STORE LIKE BUYING IN YELLOW!!! but shes selling WTF??? exploit?????
Maybe it's an incorrect message and a server/client bug? It could be that the buyer does not have enough adena and a bug (or bad translation) makes it seem like he is trying to sell the item.
