oh man dont be afraid that's only a rmah bug it is not a motive to be alert for one ban nonexistent. How someone said before when it happen , will happen. Just be afraid when you can not open d3 and you can read "your account has been banned" just at this point you can do your travel bag, not before.
Don't listen to anyone above.
I hope you read my post in time.
there is a Glitch that is going around for gold and real money buyers that when you sell or buy something sometimes if there were a lot of trades at the time. the a/h server lags.
it will cause a glitch in the system causing you to get no money for an item, or to get a item for free.
If this happens you should take the a/h transaction ID and make a ticket Asap, you can expect a ban within 2 to 4 days.
Most of the time its auto repaired/fixed.
