Blizzard is taking Diablo 4 very seriously after discovering the first major exploit. Usually, exploits give players unintended powers but do not affect other players, like bringing Eternal Realm characters into the Seasonal Realm, or dealing more damage than realistically by combining certain Aspects and class skills.

Blizzard has disabled trading between players until it is fixed because the exploit is a duplication exploit, which could ruin the player economy. The news comes from an official post on the Diablo 4 subreddit, where a Blizzard community manager said trading would be offline until the exploit was fixed.
