Great game but...

Im lowering my stars. Heres my problem: every time the challenge is to collect a certain number gems, I NEVER meet the challenge because they are not offered. I will even use my gems for the save mes but I am never offered. This weeks challenges are to collect gems, daily and weekly challenges. I already missed the daily because only 3 have been offered and today is Friday, Ive only gotten 3 gems offered for the entire week so far. If that is the challenge, then offer more gems!
