Again yesterdays payment missing...
(last payment 17.9)
Nope, just requires patience. Genesis-Mining does not have fixed payout times, but you will receive a payment for every day. It can take a bit longer. Also, opposite that, don't be surprised if you receive two payments in a relative short period of time.
Yes. Thank you for mentioning it again Mike18feb. Please understand that there are a lot of users with each mining his individual portfolio of coins. This is not a trivial system and some additional checks are important to keep everything 100% correct.
