Long ago i transmuted my golden belt into bone belt that used to drop in normal grey wolf den dungeon. While other items do allow you to retrieve whatever skin they have simply by using "convert to appearance library item" option in the context menu my belt simply doesnt have said option. When appearance tab was first introduced on preview i tried & it work just fine. Not anymore apparently for some reason. Would be nice to get a fix since bone belt is no longer available in game.
