i have recently on my account character name Briofite had the issue crop up with the AH. i posted an item for a very cheap price, accidentally a whole stack instead of a single item and single item price, and i was unable to find that item in my auctions list.
i have reloaded UI
removed all addons
restarted game with no addons loaded
i can clearly see my items listed but unless you can see the items listed on the “auctions” page you are unable to cancel the auction to be able to relist it properly. i have been messing with this for around a hour now and am posting in the hopes that the server restart will fix the issue but if not to have it recorded and possibly fixed by staff.
Cheers and thank you!
