Ripped Off on Gems after Logging in for 7 Days

I started with 125 gems when I logged on. I have logged on every day for 7 days. Yes with my bonus I am only up to 170 gems. Is this correct? I'm pretty sure it said I was supposed to receive 75 gems on my 7th day of log in, which would mean I am now supposed to have 200. :/

You receive 45 gems for logging in for 7 days straight. So yes, 170 gems is correct.

The gem bonus is 45, not 75 (This never changes since the game started). So 170 is the correct amount.
