If you remove armorchroma does it still crash?

Hello everyone!   I’ve launched a Christian Minecraft server today called “Acolyte”. Although it’s a Christian server, it’s open to anyone, but the main goal of me pursuing this was to combine two things that I love and make an area where people can talk about faith and build some cool castles. The server is meant for Java edition, 1.21.5, and has plugins such as land claiming, economy, shops, terrain generation, etc. It’s a survival / smp world, and the server address is: acolyte.mcsrv.pro   There’s a Discord server linked to it as well. It’s a place to hangout, talk about the game, have theological discussions, and hopefully meet some pretty cool people. The invite is available on the Minecraft server. I’m still new to a lot of this, and so please forgive any downtime or tweaks that I make to the server, and please give any feedback or criticism if you come up with some ideas. I truly hope you all enjoy it if you get the chance to join.   - ChedduhCheese   acolyte.mcsrv.pro

My Crazy Craft Updated pack for 1.16.5 crashes whenever I use items from Mowzie's Mobs that have animations. Specifically the ones that I have tried are the Ice Crystal and the Axe of a Thousand Metals. The crash only happens when I use the ability of it, aka right click, which triggers the animation. I should note that I added around 50 other mods to the pack, two of which are the Female Gender mod and More Player Models. Could they be the source of the crash? Here is the crash log: https://mclo.gs/ZhsC793

Hey! I noticed you're trying to register your alexandrite item and possibly set its resource location manually with setId(...). I wanted to help clarify a few things that might simplify your code and avoid errors. ✅ The issue: You're using setId(...) inside the item registration like this:   public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties().useItemDescriptionPrefix() .setId(ResourceKey.create(Registries.ITEM, ResourceLocation.fromNamespaceAndPath(TutorialMod.MOD_ID, "alexandrite"))))); But: Item.Properties does not have a setId(...) method — this line will either fail or do nothing meaningful. useItemDescriptionPrefix() is mostly used for translation keys (like "item.modid.name") but isn't needed unless you have a very specific reason. 🛠 The fix: You only need to register your item like this:   public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties())); Forge automatically handles the ResourceLocation (modid:alexandrite) based on the name passed into .register(...), so there’s no need to manually assign it. 📝 For the texture: Make sure you have this file in your resources: src/main/resources/assets/tutorialmod/models/item/alexandrite.json { "parent": "item/generated", "textures": { "layer0": "tutorialmod:item/alexandrite" } } And your texture PNG goes here: src/main/resources/assets/tutorialmod/textures/item/alexandrite.png 🌍 For the name in-game: Add this to your en_us.json under: src/main/resources/assets/tutorialmod/lang/en_us.json { "item.tutorialmod.alexandrite": "Alexandrite" }   Note: if im wrong about the issues you are encountering, i apologize.
