Hi!
I am facing the same situation.
In Dash Ninja is inactive.
In Dash Central: Your masternode dropped off the masternode list and is not enabled!
Dash wallet masternodes tab says: ENABLED.
Dash wallet masternode list says: ENABLED.
dashman says: queue position nn/4428 (and moving down).
Your post makes me less anxious...
Edit: Mine is solved!
Stopped dashd, deleted *.dat, restarted dashd and issued start-alias.
