Lineage player sued NCsoft earlier this year. After unsuccessfully petitioning to have her rare Jin Myung Hwang's Conduct Sword restored by claiming her failed enchantment attempt (which destroys the item in Lineage) was accidental, the South Korean player sued NCsoft. The extremely rare sword could sell for $28,000.
Unfortunately, the plaintiff's game log showed that she bought special items to improve her odds at enchanting and she continued to enchant other items even after the destruction of the rare sword. The court's ruling was not in the player's favor, noting that even if it was a mistake, NCsoft was not required to restore the item.
