    I have not been using Bukkit in a while, so I am not up to date about a lot of things. What causes this warning? It causes a lot of server lag. Is there any way around it?

    > Initializing Legacy Material Support. Unless you have legacy plugins and/or data this is a bug!

    Here is my code:

    private void init(Market market) {
            String title = market.getSector().getColor() + market.getSector().getName() + Messages.format(" &7Market Data");
            this.inventory = Bukkit.createInventory(null, 6 * SLOTS_PER_ROW, title);
            // sort alphabetically
            List<Material> items = new ArrayList<>(market.getItemValues().keySet());
            for (Material item : items) {
                ItemStack button = new ItemStack(item);
                ItemMeta im = button.getItemMeta();
                // im should never be null
                if (im != null) {
                    String itemName = item.name().toLowerCase().replace("_", " ");
                    // capitalize first letter
                    itemName = itemName.substring(0, 1).toUpperCase() + itemName.substring(1);
                    im.setDisplayName(Messages.format("&b" + itemName));
                    List<String> lore = new ArrayList<>();
                    lore.add(Messages.format("&7" + Bank.formatCurrency(market.getItemValue(item))));
    The warning does not show if I just comment out the final addItem call.

    @MCMastery What version are you running? What version are you building with?

    Did you include the "api-version" tag to the plugin.yml? If not, you need to include that in order to use 1.13+ items.

    I did include "api-version: 1.15". But I forgot Spigot is not supported here so I'll go over there
