Faulty treasure hunt achievement

[MangAnimE001]

Main reason I got this game was for my 15th chest in treasure hunt, got over 37 on beach (this map --> http://www.users.on.net/~g_section9/img/flightControl_win32%202010-12-21%2005-09-09-65.jpg ) 30-45mins before the hunt ended, my score showed in global leaderboard, kept refreshing treasure hunt page (also continued to play game) but the chest didn't unlock & now the treasure hunt page is gone & I didn't get the 2nd TF2 hat nor another entry into the treasure hunt.

Hopefully this will be resolved.
