Polmine question about rewards

[Cheeseater]

Hi

Can't seem to find anyway to contact them and thought maybe someone would have some insight. Moved a dragon miner over to polmine to give them a try having some real bad luck at my usual watering holes.

My rewards took a huge drop after the first two blocks and the total hash has remained the same. Any Ideas?

Thanks
