theres an exploit that allows you to reset your mn with a script and move to the front of the queue and steal rewards, masternodes are paying nothing at the moment and its been this way for over a week.
Yep, being worked on by team as we speak. This from Carsen:
"Updates for MNs will be coming soon, there is currently no ETA, but I do hope to get to it ASAP!
v3 of Denarius is still in progress as well with Ring Signatures, Tor, and I2P.... For those wondering, I will never leave Denarius, stay loyal!"
