Trading Exploit still alive and well today, people make a market on both sides of the map and trick the trading post into letting them pick up the gold right away and drop it off at their other market across the map, skipping half the trip.
This was not on PUP right?
Nope, on live, fun for everyone!
This is one that I believe is fixed for the upcoming Season 5 update. If you see any trade exploits after that, please do let us know. Thanks!
