There was an issue with some of the mounts released with patch 7.3 which
allowed them to be traded. Since the patch this issue has been resolved and
can no longer be traded. We do not have the ability to move mounts or remove
this restriction.
一些補丁7.3發布的坐騎有一個問題，允許他們進行交易。 由於補丁此問題已解決，不能
再進行交易。 我們(官方)無法移動坐騎或取消此限制。
希望目前仍在為尾王座騎努力的朋友們注意... 不要不小心分錯人了....
