Hello,

I'm reporting an issue,

I currently hold 5 gold, 3 silver , 4 bronze cups and 5 Medal with total of 55 points, but I have not yet recieved any achievements but one.

achievements :

Collect 1 golden cup

Collect 10 cups and medals

Contribute 50 Points to your team

Coming Soon : Collect 50 Cups and Medals on LGA775

I'd like to know the reason for that.

Thanks in advance,
