The team has finally worked out a fix, and some time today the currency exchange is expected to be brought back online. “[Tuesday’s]Â patch includes backend fixes that have been implemented for the currency exchange,” the studio said. “We are planning to re-open this feature as soon as we finish implementing some additional server changes, and estimate the marketplace to be back online tomorrow (June 28th). Â Thank you all for your patience!”
A few other hotfixes over the past two days include a minimum price on the auction house to post items, a few animation tweaks, and corrections to wrong rewards being handed out in level 50 dungeons.
