First, I placed a max bid of 15,000 on an amulet.
The live bid became 847 in my auctions tab.
Then I browsed around and saw an amulet at say around 956.
I figured, 'why not bid on both? I have to win one of them.'
So I placed a max bid of 15,000 on that amulet as well.
In my auctions tab, the first amulet jumped to 15,000. I was "not winning" this item. And no "2nd amulet" appeared in the auctions tab.
I believe I had effectively bid against myself, forcing my max bid to be reached.
I should think bidding against yourself is a bug. So I hope I have the right forum to submit this 'error'. I don't care to get my fake money back, chances are I'll lose the auction, and get it back that way. However, I thought this might be a rare occurrence, and would share.
