Cataclysmic Lumberjack

It appears the reward, which claims to allow for Mounted Lumber Harvesting in Cataclysm Zones, does not currently function properly.

I switched flight style to Steady Flight, and get the error "You are flying." Relog did not solve this issue. Tested in Twilight Highlands.

For those working the Midnight pre-patch Lumber Achievements, use Twilight Highlands for the Cataclysmic Lumberjack Achievement. Any of the green areas on the map. Lots of Lumber available. Not much contested with roaming mobs. Use the areas both north and south of the river that runs just north of BloodGulch. GLHF.
