Hello as I PM'd harald already regarding this, I'll make a thread too since I'm not the only one ending up in trouble with the new system.
Happens the following, checked the forum/weby regarding info about this, and since nothing at that point was revealed or any protip on the options, I tested the Auction System with a random item, and was able to cancel the auction.
Since the testing was a success, I proceeded to the auction creation of a Lordly Red Tunic over Mail both in order to try a new type of trading, other than the usual trade option spam.
Was surprised to see that I couldn't cancel it, which might end up on losing a +3 lordly piece to a few bunch of coppers (since no starting bid option is still on track), and neither could I trade it on the market, or even Equip it, since it's no longer in my possession.
By searching the auction market a bit, I noticed the same will happen to several of the members that started auctions like this, uninformed.
Is there a way for me to cancel the auction and retrieve the item before the "hunters" exploit this?
Thank you for your time, cheers.
