I've been running nodes for a few months.  On friday there was a huge spike of generated fees (2,724.7500037) (nice payout). Today restarted a node and it can't sync.   Noticed that NOMP miner is not present today who was fastest miner (4-1-2018) (https://chainz.cryptoid.info/ent/#!extraction).   My nodes that haven't been restarted say they are in sync.   Wondering since NOMP dropped out or this has to do with upgrade (0.12.1.17) ?

Anyone?
