Guys,

This is not a bug or problem.

They did with reward system same as they did with free rolls. If you don't have more than 50 USD in your account you will got your rolls reduced 50% and will not be able to activate 100 RP per roll or 1000% bonus.

As i said before, it's time to say goodbye.

Edit:

If you don't have more than 50 USD you will be forced to make deposits or lose tons of satoshis on mutiply game and lottery system to get your account working like before.
