I have traded a bunch of Legendary items at the exchange for scrip. I still have some left but the machine has no currency left. How long does it take before the scrip replenish so I can trade more weapons again?
I think it takes 20 hours,which is the same as it takes for regular NPC vendors in the game. You might have to log out and in to make the scrip show back up again. You can be safe to go with 24 hours. So if you trade in legendaries at 5pm, you can be sure that it will have restored by 5pm the next day
