Did these sancs in question crash, or fork, or are they still synced guys?
My masternode process was still running, but listed as expired in my wallet. When running commands I got this as output:
./biblepay/src/biblepay-cli mnsync status
error: couldn't parse reply from server
./biblepay/src/biblepay-cli getinfo
error: couldn't parse reply from server
./biblepay/src/biblepay-cli stop
error: couldn't parse reply from server
After killing the biblepayd process and starting it back up, everything was fine. I'm still running 1.1.3.8
