[1.8] ChestGenHooks not working with mod items!

I'm trying to add some mod item loot to a chest but the items never spawn correctly (it just spawns useless missing texture non-items)  in the chest. The items themselves are fine other than the ones that spawn in chests.

Here is what I mean:

ChestGenHooks in public void load(FMLInitializationEvent event)

 ChestGenHooks chestcontents = ChestGenHooks.getInfo("RelicChest1"); // create registered ChestGenHooks
     chestcontents.addItem(new WeightedRandomChestContent(mystical_epicarno_mod.Epicnite, 3, 4, 6, 10)); // 4-6 cocoa beans
     chestcontents.addItem(new WeightedRandomChestContent(  Item.getItemFromBlock(mystical_epicarno_mod.RelicTNT), 1, 1, 6, 10)); // 4-6 cocoa beans

     chestcontents.addItem(new WeightedRandomChestContent(new ItemStack(mystical_epicarno_mod.Tack, 1, 15), 2, 5, 20)); // 2-3 black wool

  

     chestcontents.setMin(7); // inclusive
     chestcontents.setMax(9); // exclusive

ChestGen in WorldGenCode

  BlockPos blockpos2 = new BlockPos(i + 8, j + 2, k + 2);
        TileEntity tileeentity1 = world.getTileEntity(blockpos2);

        if (tileeentity1 instanceof TileEntityRelicChest)
        {

                WeightedRandomChestContent.generateChestContents(rand, ChestGenHooks.getItems("RelicChest1", rand), (TileEntityRelicChest)tileeentity1, ChestGenHooks.getCount("RelicChest1", rand));
           
        }
