This is along the same lines as the bug for the boots/gloves enchant.
The title says "Green Lumberjack Shirt" but the pattern says it makes a Yellow Lumberjack Shirt.
Pattern: Green Lumberjack Shirt - Item - World of Warcraft
And Blizz says they didn't rush the xpak. :lol: Lots of little bugs and screwups like this.
