Mythic will be temporarily disabling Warhammer Online's in-game auction house beginning Friday afternoon. The functionality is being removed in order to patch in the latest tweaks coming your way with the 1.3.6 update. The patch brings a streamlined auction house UI, as well as a standardized 48-hour auction duration. Additionally, pricing has been simplified to buy-out only.
Previously existing auctions will continue to be available featuring the bidding and buy-out functionality, but new auctions will not be available until after the patch. Check out the official announcement at the Warhammer Herald.
