I've been trying to find whether there are any special instructions for upgrading MNs hosted remotely on moocowmoo's masternode.me service. So far I haven't found anything, but it seems at least one locally-upgraded wallet (Dash Core version v0.12.1.0 (64-bit)) is running as dashd v0.12.00.58 according to its stats page on mastercode.me

The usual fix for that sort of thing is a "masternode start" command (I think) but it reports:
{
  "overall": "Successfully started 0 masternodes, failed to start 0, total 0",
  "detail": {
  }
}

Suggestions welcome - thanks!
