I'm getting an error when loading up my modded world: "Errors in currently selected datapacks prevented the world from loading. You can either try to load it with only the vanilla data pack ("safe mode"), or go back to the title screen and fix it manually."

This error occurs after I open the save, return to title screen, and try opening the save again. In which, it will throw this error at me.

It appears to only happen with this save - I can load and reload other worlds without issue, which makes me think that something I recently done in my world somehow corrupted it? The last thing I did was work on my house so I placed a lot of modded blocks. I don't know if that could be the cause.

Every time I open up a copy of my save, I can open the world. But then I try re-opening it and the error occurs. So something is going on in between me exiting the world and trying to reopen it.

I tried deleted the level.dat file and replacing it with level.dat_old (renaming it to level.dat) as I saw in another thread, but that doesn't work. I am playing on a custom modpack that I made (no datapacks) and this error has occurred 30 days into my play-through of the world. It has not happened before.

Here is the console log from MultiMC after I launch my game, open a new copy of the save, quit to title screen, and attempt to open the save again. https://paste.ee/p/9CvEU

There is an issue with an entry in your level.dat

  

java.lang.RuntimeException: Tried to read NBT tag with too high complexity, depth > 512

Maybe check this file with an NBT editor

Okay, what should I be looking for? Anything in particular?

I have no idea - maybe some world generation settings

 

Or check the level.dat for the seed

Copy the seed, create a new world with the same settings and the seed

Then copy level.dat, level.dat_old and session lock from the new world to the broken one

Delete the new world and test the old world again

Try my Modpack

Great news! That actually fixed it! I am forever grateful for your help man, you seriously saved me. Here is exactly what I did in case others have the same issue:

  • Create new world (using the re-create world function didn't work for me.)
  • Use the same seed from original world, make sure my game settings are all the same like difficulty, gamemode, etc.
  • Load in to world.
  • Exit world.
  • Go to save folder, copy level.dat, level.dat_old, and session.lock
  • Go to original broken world's save folder, delete those three files and paste in the ones I copied.
  • Load into original world. I relogged a few times just to check the error wouldn't return. Seems now to be working just fine! I'll be making sure to make more frequent backups and if this problem ever occurs again, I'll try out your solution once more.

Thank you again TileEntity!

      Help resolving the root cause for Exception: Item id not set

      By socrates3992 · Posted

      I will keep adding to this thread with more information in case anyone can help, or at the very least I can keep my troubleshooting organized. I decided to downgrade to 54.1.0 in the hopes that this would fix the issue but it didn't. At least now I am on a "recommended" version. The crash report did confirm my earlier post that the Exception is coming from effectiveDescriptionId(). I'll continue to see if I can find a way to set the ID manually.   Caused by: java.lang.NullPointerException: Item id not set         at java.base/java.util.Objects.requireNonNull(Objects.java:259) ~[?:?]         at TRANSFORMER/[email protected]/net.minecraft.world.item.Item$Properties.effectiveDescriptionId(Item.java:465) ~[forge-1.21.4-54.1.0-client.jar!/:?]         at TRANSFORMER/[email protected]/net.minecraft.world.item.Item.<init>(Item.java:111) ~[forge-1.21.4-54.1.0-client.jar!/:?]         at TRANSFORMER/[email protected]/com.example.shotgunmod.ShotgunItem.<init>(ShotgunItem.java:19) ~[shotgunmod-1.0.0.jar!/:1.0.0]         at TRANSFORMER/[email protected]/com.example.shotgunmod.ModItems.lambda$static$0(ModItems.java:15) ~[shotgunmod-1.0.0.jar!/:1.0.0]         at TRANSFORMER/[email protected]/net.minecraftforge.registries.DeferredRegister$EventDispatcher.lambda$handleEvent

      Custom Modpack crashing upon "WorldLoader" load screen

      By WeeWoo · Posted

      Link to Crashlog: https://pastebin.com/bKqH9fx2 Trying to set up a custom mod pack, was going smoothly up until recently as the WorldLoader screen, (the one that appears when you select "create new world" in Singleplayer), was clicked to test that it was running fine. Most Recent Few mods added were; - Create (+ its addons) - Immersive Weathering [Forge] I've tried all I could think of since loading up the game worked fine and I've never had this issue before.  Any help is appreciated.

      Help resolving the root cause for Exception: Item id not set

      By socrates3992 · Posted

      Digging in to the source, in this case net.minecraft.world.item.Item.Properties, I see these functions are the error source:         protected String effectiveDescriptionId() {             return this.descriptionId.get(Objects.requireNonNull(this.id, "Item id not set"));         }         public ResourceLocation effectiveModel() {             return this.model.get(Objects.requireNonNull(this.id, "Item id not set"));         } Can anyone share more information on how to set the Id properly? Is this something I have to do explicitly by calling the setId() function? My understanding is the ID is set implictly with these calls:       public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, ShotgunMod.MODID);     private static final Item.Properties p = new Item.Properties().durability(100).stacksTo(1);     public static final RegistryObject<Item> SHOTGUN = ITEMS.register("shotgun", () -> new ShotgunItem(p)); From net.minecraft.world.item.Item.Properties;  public Item.Properties setId(ResourceKey<Item> pId) {             this.id = pId;             return this;   } Thank you for your help
