Hello,

I tried modifying a vanilla loot table following the instructions it Forge documentations. However the game fails to load the modified loot table.

 

Code: 

@SubscribeEvent
	public static void onLoottableLoad(LootTableLoadEvent event)
	{
		if (event.getName().equals(EntityType.ILLUSIONER.getLootTable()))
		{
			LootTable table = event.getLootTableManager().getLootTableFromLocation(new ResourceLocation(WTImprovements.MOD_ID + ":injects/illusioner"));
			LootPool pool = table.getPool(WTImprovements.MOD_ID + ":totem_of_decoy");
			event.getTable().addPool(pool);
		}
	}

 

Loot to add 

{
	"type": "minecraft:entity",
	"pools": [
		{
			"name": "wt_improvements:totem_of_decoy",
			"rolls": 1,
			"entries": [
				{
					"type": "minecraft:item",
					"name": "wt_improvements:totem_of_decoy",
					"functions": [
						{
							"function": "minecraft:set_count",
							"count": {
								"min": 2.0,
								"max": 3.0,
								"type": "minecraft:uniform"
							}
						}
					]
				}
			]
		}
	]
}

The JSON itself seems to be fine. Does anyone know what's wrong with the loot table?

Thanks for any response.
