It works outside of the Garrisson, but inside, it’s broken, whether my Druid is Flying on the Ground or in default form.
I do get the Herbs sent back as Recovered by in-mail system, but it’s annoying to do it that way.
Also, using a PickAxe in the Garrisson Mine no longer speeds up mining for my non-Miners as much as it did before (My Herbalist, non-Miner Druid in Catform almost got the nodes immediately before the pre-patch, even my Mining Dwarf was not as fast).
May have something to do with changes in Profession related Speed updates ?
