Recently, Arc Raiders introduced a major Cold Snap update and the ability to go on an expedition (a local voluntary wipe system).
Players noticed that something happened to the drop rate of blueprints. They began to drop so often that members of the Arc Raiders community began to boast about their filled inventories.
For farming, 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).
