What were the 3 or 4 masternodes doing? I had times in the last few days where my weight was higher than the network weight. Nonsense. It's just broken.
I'm not sure the masternodes can move the blockchain without stakers; but if your stake weight was higher than the network weight, and the blockchain still didn't move, then maybe things are broken.
Personally I'm just seeing things moving extremely slowly, not exactly broken - bought some cheap coins from Yobit, and am trying to make a masternode (total cost: 18 cents, why not?). The only problem is waiting for 15 confirmations before starting the MN - it's literally taking all night.
