A small update
Masternodes with the status in WATCHDOG_EXPIRED don't worry we are working on it, what happened is someone ported and enabled sentinel for their node and we are now working on porting sentinel to SOV or hoping the user who already did will donate their source. Give us 24-48 hours as we are working currently to port sentinel so that you can easily add it if you wish to have your nodes showing as ENABLED again.

This has not affected Masternode rewards just for the time being any watchdog_expired node needs to be considered as Enabled.
