Read this on mmogfails today, it was discovered by Dmanthey.
Finally is yet another AH exploit. This allows you to buy out whatever auctions have expired for free. Thanks to Dmanthey and many others for this information.
Lol go try this out. Wait till an auction is about to expire, when the timer counts down to 1, wait a few seconds and bid/buy it out. You just got the item for free. No AD lost. Pretty sure it screws over whoever was the buyer or seller was. Not sure though. Epic programming win from Cryptic!
Anyone else got some freebies before this was patched out? I camped the most expensive stuff possible lol. Now time to resell and buy some Zen.
