This is the config that was working before the update but no longer works not sure what I need to change.  I put this in a JSON validator just to make sure I didn't make any mistakes but still deletes my config every time I reload the plugin.

{
  "Detailed_Analysis": false,
  "Custom_Items": [
    {
      "shortname": "hq.metal.ore",
      "amount": 2,
      "chance": 100.0,
      "valid": true
    },
    {
      "shortname": "crude.oil",
      "amount": 2,
      "chance": 100.0,
      "valid": true
    },
    {
      "shortname": "stones",
      "amount": 2,
      "chance": 100.0,
      "valid": true
    },
    {
      "shortname": "sulfur.ore",
      "amount": 2,
      "chance": 100.0,
      "valid": true
    },
    {
      "shortname": "metal.ore",
      "amount": 20,
      "chance": 100.0,
      "valid": true
    }
  ]
}

Change "Detailed_Analysis" to "Display Detailed Analysis" and "Custom_Items" to "Custom Items"

Thanks Biscuit that fixed my problem.
