Blizzard disables trading in Diablo 4 for the third time in a year, as another dupe bug wreaks havoc on its economy
Diablo 4 has, once more, had to disable trading due to a duping bug—the third time in one year, albeit just barely, as announced on the Diablo 4 forums by community manager PezRadar:
«We will be disabling trading in Diablo IV while we investigate a possible duplication issue. We apologise for the disruption and will provide updates on when we will have trading available again once we further investigate and identify any issues we need to resolve.»

On August 15 2023, the company had to do the exact same thing. A similar suspension occurred in October 2023, making this the third time in a single year it's happened—in fairness, just barely.
The dupe, as outlined by YouTuber Sliver of Time, was first properly broadcast on streaming website bilibili (thanks, GamesRadar)—appearing to weaponise the player stash and the power of friendship.

Take Star Wars: The Old Republic, for example, which had low-level gear going for millions and millions of credits last year.
Blizzard stepping in and slamming the emergency bunker door shut makes sense, regardless of whether or not the dupe is widespread enough to've had an impact. Developers can suss out the exact nature of the glitch later, but for now, quarantining the economy makes
