I have over 300 mounts, but it isn’t giving me credit for even the 100 and 250 achievements.
EDIT: Upon looking through more of my achievements, I am missing SO many! I am a vanilla player and have had alchemy on my main since day 1 of playing, yet my alchemy achievements are all empty and incomplete. The same goes for other professions and many other categories. Even parts of my map are unfilled and I have totally explored EVERY SINGLE LAST LITTLE NOOK AND CRANNY of this game. It’s one of the first things I do at an expac launch, explore everything and grab every flight path, etc.
This patch totally screwed my entire account over.
