I'm playing hardcore and this happened to me today.
I've bid 1.5m gold on an item but the bid didn't work because of the heavy transaction on the AH. So I bid another 1.5m on the same item...when I looked at my transaction I had 3m less gold in my stash and I was outbid by someone which also put 1.5m
the transaction said: Not winning......your bid: 1.5m.....current bid: 1.5m...
Result, I've outbid myself, I didn't win the item, and I didn't get my 1.5m back.
Please help me, thx :)
