Config Changes not being read?

I'm using Rust on a Portainer install with a volume.

I've added the PlayerRanks plugin, reloaded Oxide and can see its created a PlayerRanks.json file under the config folder.
I'm then updating and saving this config file to point at my MySQL server and then running o.reload PlayerRanks

I can see that it reloads the plugin

however it doesn't mention anywhere about the MySQL database.

If I then run playerranks.save it only seems to save locally:

[PlayerRanks] PlayerRanks local database was saved.

Calling 'CmdSave' on 'PlayerRanks v2.1.9' took 121ms

Anyone have any ideas?  Pretty sure I've tried this before, and it'll connect to the MySQL DB and create the table, or fail and tell me the SQL connection failed, however I'm getting neither?

Hey yep

  "MySQL": {
    "useMySQL": true,
    "autoWipe": true,
    "sql_port": <redacted>,
    "sql_host": "<redacted>",
    "sql_db": "localtest",
    "sql_user": "<redacted>",
    "sql_pass": "<redacted>",
    "tablename": "playerranksdb",
    "LBtableName": "playerranksLeaderdb"
  }

I think this can be closed now.  For whatever reason it didn't want to work, but has been working fine now for a few weeks
