There is a npc at Varanas Central, whom you can trade dias for gold. But I failed to find the npc who exchanges dias for gold. There is also an option to buy gold/dia in "Money" section of Auction House but it doesnt seem to be available.
What's the reason for this removal and is there anything we can do to bring it back?
It'd be really helpful to be able to buy small amount of dias for urgent situations.
