Went through the same procedure as setting up my other masternodes.

Using the latest version...
    "version" : 2010203,
    "protocolversion" : 70701,
    "walletversion" : 61000,

Sent 10000 to the address, made the private key... updated masternode.conf, restarted wallet.

The transaction does show up in this list "darknet-cli listlockunspent"

But is not in in the list "darknet-cli  masternode outputs"

Unsurprisingly, trying to start the masternode shows...

"errorMessage" : "Could not allocate vin ...... for masternode ........onion:51472"

Any ideas what went wrong here?
