I see some RICHMEN are trying to build masternodes(with IP 13.xx.xx.xx).
Those masternodes just can be seen as "ENABLED", but Active time always keeps to "00m:00s"
I think U should add a line to the file "puzcoin.conf" (in data folder):
externalip=YOURIP
then restart the QT client,and click "start" of "my masternode".
Be lucky!
