I don't know if anyone else saw it, but there was a period from around Sept-Oct last year where my rogue could track both mines and herbs at the same time. I just had to switch tracking modes and the previous one stayed on while the other was active. It stopped working around the time when the expansion came out. Never had any idea why that worked or why it stopped. It worked for a month or two, so it didn't seem to be just a fluke glitch, I thought it was a hidden "buff" to tracking. Heh.
