Recently, a major Cold Snap update was introduced for Arc Raiders, along with the ability to go on an expedition (a local system of voluntary wipes).
Players noticed that something had happened to the drop rate of blueprints. They started dropping so frequently that members of the Arc Raiders community began boasting about their filled inventories.
To farm, they go to maps where the new "frost" weather mechanics are active. There is an opinion that this was not intended by the developers, but is a common bug.
This event has another effect: entrepreneurs on the black market are trying to sell blueprints for Arc Raiders. Now the volume of supply may increase sharply, which will prevent high prices from being set (previously, the cost of some lots could exceed the price of the game itself).
