This is pretty specific but does anyone remember in one of the Runescape open betas back in the day there was a duping bug? I think involving a chest? If I recall it was really easy to do and by the end of the beta like everyone had totally jacked up gear Of course it all got reset eventually since it was just a beta but I recall it being pretty hilarious to play during that period
They eventually added a mechanic in game that consumed the rings for something else as a way to remove the rings from game without deleting at will.
