Old School RuneScape faced another economy-compromising dupe bug this week following the release of new content on September 25. Players found a way to generate countless valuable potions from thin air, forcing developer Jagex to disable all trade, yank the MMO's servers offline, and ultimately roll them back to resolve related issues.
A loose timeline of events starts at 1:10am ET today, October 1, with a prominent Reddit post from user FactFetishist. "Potion storage has a dupe bug," the player declared. "Good job, Jagex." This bug was obviously discovered before this point, but this is the earliest public acknowledgment I can find.
