Modding Help Starmap upgrading

Has anyone figured out how to add the starmap upgrades into one item? I've tried and failed.
This causes the engine to ignore the item:

Code:

{
  "itemName" : "ftlmap",
  "rarity" : "Legendary",
  "inventoryIcon" : "tier2engine.png",
  "image" : "tier2engine.png",

  "shortdescription" : "FTL Upgrade",
  "description" : "I can use this to upgrade my ships engine, allowing flight into all sectors.",

  // Remember you can override this with parameters, no need for more than one
  // unlock item
  "sectorUnlock" : "beta",
  "tierRecipesUnlock" : "tier2",
  "sectorUnlock" : "gamma",
  "tierRecipesUnlock" : "tier3",
  "sectorUnlock" : "sectorx",
  "tierRecipesUnlock" : "level31",
  "unlockMessage" : "Starmap Updated. New data has been uploaded to your ships navigation systems. Select the beta sector from the top of the navigator when in galaxy view to advance."
}

The engine recognizes this item, but it turns out to perfectly generated green block that does nothing.

Code:

{
  "itemName" : "ftlmap",
  "rarity" : "Legendary",
  "inventoryIcon" : "tier2engine.png",
  "image" : "tier2engine.png",

  "shortdescription" : "FTL Upgrade",
  "description" : "I can use this to upgrade my ships engine, allowing flight into all sectors.",

  // Remember you can override this with parameters, no need for more than one
  // unlock item
  "sectorUnlock" : "beta, gamma, sectorx",
  "tierRecipesUnlock" : "tier2, tier3, level31",
  "unlockMessage" : "Starmap Updated. New data has been uploaded to your ships navigation systems. Select the beta sector from the top of the navigator when in galaxy view to advance."
}

 

You can only unlock one sector at a time with these items.
However, it might be worth testing a jSON array. I doubt it though.

Code:

  "sectorUnlock" : [
    "beta", "gamma", "sectorx"
  ],
  "tierRecipesUnlock" : [
    "tier2", "tier3", "level31"
  ],

 

I'll give it a shot and report back.
