Went to get Herbing KP on my Shaman today and flew around for quite awhile before realizing that for no apparent reason, her Track Herbs was turned off.
I know I didn’t turn it off, because literally the only thing I take her out into the world to do IS gathering KP and the 2 treasures weekly.
EDIT: It also doesn’t help that fertile soil does not appear to count as an “herb” and tracks even with herb tracking off, so when you see icons for soil but no herbs, you have no reason to think the game decided to randomly turn tracking off.
