Got a new warning at bottom corner of wallet No sync checkpoint received for quite along time yet there is a check mark showing it is syned, whats up with that now?
This message doesn't mean that something is wrong on your end, it means that Neucoin haven't published any sync-checkpoint yet. You should also check if your wallet is unlocked for minting and you should be good.
