250 mount achievement

Has any1 recently got 250 mounts achievement? I am missing 12, and last night i've heard that achievement might be bugged and you don't get mount reward from it. So should i bother with stupid dailies in icecrown for argent tournament mounts or just give up :/

I have 270 mounts but no achievement for 250.

I got 277 mounts .... the reward is working but you have to change factions from the site to learn it

250 mount achieve was added in WoD. Doesn't exist in mop.
