Have i missed something happening in Ravencoin mining ?

Hi there

I am currently mining Ravencoin with 4 x rtx 2080 and a 1660ti so overall a Hashrate of 120MH/s.

For couple of days i received about 10coins every 3-4hours, but now i am only getting 10coins every 6hours…

Has something happened in the Network that i am not aware of?
