When they uwarp map item ? 
Or when they loot chest or ? 

"Coins": [
    {
      "CustomStackSize": 0,
      "ItemDisplayName": "TOME PT (4)",
      "ItemShortname": "xmas.present.small",
      "SkinID": 2863539914,
      "MinItemPerCoin": 1,
      "MaxItemPerCoin": 1,
      "LootTable": "goldcoin",
      "LootTables": {
        "goldcoin": [
          {
            "Economy": "Item",
            "PluginName": null,
            "DisplayName": "TOME PT (4)",
            "Shortname": "xmas.present.small",
            "SkinID": 2863539914,
            "MaxItemAmount": 3,
            "MinItemAmount": 1,
            "Probability": 50.0,
            "IsBlueprint": false
          }
        ]
      },
Problem is bcs you made that custom item from another item as coin from my plugin...
So you changed logic from that item ...just delete it from coin...
You can give that item in coin but dont call it same as loot item ...
As you can see you call same name ,same shortname same skin id for coin and for loot item ..

example how to use it :
"Coins": [
    {
      "CustomStackSize": 0,
      "ItemDisplayName": "Gold Coin",
      "ItemShortname": "xmas.present.small",
      "SkinID": 123,
      "MinItemPerCoin": 1,
      "MaxItemPerCoin": 1,
      "LootTable": "goldcoin",
      "LootTables": {
        "goldcoin": [
          {
            "Economy": "Item",
            "PluginName": null,
            "DisplayName": "TOME PT (4)",
            "Shortname": "xmas.present.small",
            "SkinID": 2863539914,
            "MaxItemAmount": 3,
            "MinItemAmount": 1,
            "Probability": 50.0,
            "IsBlueprint": false
          }
        ]
      },
So as you can see coin item is diferent than that custom item ..

Changed Status from Pending to Not a Bug

Thank you!
