After so many methods to duplicate gold in New World, the dev team decided to shut down all sorts of transfer methods in the game, such as the Trading Post, Player to Player Trading, Coin Transfer and the Guild Treasury while they are working on a fix.
We are aware of a possible gold duplication exploit that has been circling and we are temporarily disabling all forms of wealth transfer between players (ie. sending currency, guild treasury, trading post, player to player trading).

The team is working on a fix, but no ETA has been offered for when the features will be enabled again. An update on the matter should be posted shortly.
We’ve identified an exploit and will be banning individuals who were using it. We will have trades off for tonight while we work through and test a fix for the problem. A patch for this issue will be released as soon as possible. We will have another update in the morning Pacific time.
