Glad to see you act so fast but really all the fuss for 9 active miners contributing less than 1KH/s hash, finding 1 block a day of 8 coins seems a bit over kill.
Most of the pools are dead. Rented hash attack did more damage to cryptonight coins that the so called bug.
346.66 KH/sec total network now and for a long time.
My theory is it's an attack from a government or rival coin. I think they're spending way more money on rented hash, for a long time, then they stand to make from coin. I think XCI has the same issue.
