I have 2-3 bases for each difficulty, but plugin spawn only one "First" , but not additional.

All files need to be valid copypaste files that you can /paste

I have additional bases base2 and base4.... but plugin use only base1....

"Raidable Bases": {
  "Buildings": {
    "base1": {
      "Additional Bases For This Difficulty": {
        "base2": [{
            "Option": "stability",
            "Value": "false"
          },
          {
            "Option": "autoheight",
            "Value": "false"
          },
          {
            "Option": "height",
            "Value": "1.0"
          }
        ],
        "base4": [{
            "Option": "stability",
            "Value": "false"
          },
          {
            "Option": "autoheight",
            "Value": "false"
          },
          {
            "Option": "height",
            "Value": "1.0"
          }
        ],
        "base3": [{
            "Option": "stability",
            "Value": "false"
          },
          {
            "Option": "autoheight",
            "Value": "false"
          },
          {
            "Option": "height",
            "Value": "1.0"
          }
        ]
      },​
