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.
一些补丁7.3发布的坐骑有一个问题，允许他们进行交易。 由于补丁此问题已解决，不能
再进行交易。 我们(官方)无法移动坐骑或取消此限制。
希望目前仍在为尾王座骑努力的朋友们注意... 不要不小心分错人了....
