1.8.8 Holographic Displays Issue

Hello! So I've recently wanted to add Holographic Displays but I've run into an issue. So I've been using this method to loop through a list to get each of the prizes from a crate:

Spoiler: Code

Code (Text):

public static void registerCrazyCratesPlaceHolders(me.badbones69.crazycrates.api.objects.Crate c) {
                HologramsAPI.registerPlaceholder(plugin, "%ccaddon_rewards_" + c.getName() + "%", 5, () -> {
                    me.badbones69.crazycrates.api.objects.Crate crate = cc.getCrateFromName(c.getName());
                        if (crate.getPrizes().size() <= i) {
                            i++;
                            return crate.getPrizes().get(i).getDisplayItem().getItemMeta().getDisplayName();
                        } else {
                            i = 0;
                            return crate.getPrizes().get(i).getDisplayItem().getItemMeta().getDisplayName();
                        }
                     
                        }
                        );  
         
    }

And I get this error

Anyone have any clue? If you need more information just respond! And I've checked everything while doing this nothing is null

 

It isn't MY line either its HD's but:

Code (Text):

ConsoleLogger.log(Level.WARNING, "The placeholder " + placeholder.getTextPlaceholder() + " registered by the plugin " + placeholder.getOwner().getName() + " generated an exception while updating. Please contact the author of " + placeholder.getOwner().getName(), t);

 

Nope nothing, but I've found the issue but I don't know how to get around it, it's the i variable/ArrayList.get() that is not working with the PlaceHolderReplacer
