Sounds about like I thought (I was the DK above. Idk why it was on that toon). Have to try and get mounts on your toon with the most mount count for it to do a recount.
Bummer. Dungeon mount farming on a slow pally can be rough since they’re so slow. But, I guess it only matters if getting the mount count would actually finish off your next achieve. For me, going from 327 to 330 doesn’t really matter. But as you inch closer to the next mile stone, it starts to matter more.
