On 15 March 2011, an update to the ring of wealth introduced new teleport abilities for the ring and made the ring notify the player when it increased the chances of obtaining a rare drop. Within half an hour of the update, players discovered that while in lootshare, the effects of the Ring of Wealth stacked. This allowed players to obtain extremely rare items consistently.
Players were able to get rares such as spirit sigils as a 100% drop from the Corporeal Beast. The day after the glitch, Mod Mark personally apologised for what happened. After Jagex reviewed the bug, they promptly fixed it, and ring's unique ability stopped stacking in lootshare mode.
