Not sure if I’m doing it wrong, but I posted an auction of an Infernal Guardian the other day.
Maybe… one or two days ago? Maybe more, I don’t really remember.
Anyway: In the Auction house it is still listed in “My Sales” and I have not recieved any notification that the sale has ended, nor have I recieved the deposit for the auction back, but if I search for it, I don’t see my auction listed among the other helldogs for sale.
If it’s been over 3 days you need to manually cancel the sale by right clicking over it to get your item back. Then you can repost at a lower price point.
