I accidentally loaded a string duper within lazy chunks and it caused 8000+ entities to render without being able to despawn. I'm trying to find a way to remove the items on the ground, however NBTexplorer hasn't been helpful since I'm playing BnC Advancement pack through the Curse Forge Launcher. I can still enter the world but loading the chunks crashes every time.
First, make sure to back up your world before trying anything, in case you get stuck in a situation where you are unable to recover.
You could enable cheats (via NBTExplorer if you don't already have them enabled), give yourself a repeating command block and place it close to the item pile (without loading it in) and add this command to the command block:
If you were duping a type of modded string, you want to replace the
id property (
"minecraft:string") with the type of string you are trying to clear. If it was multiple types, you can either use multiple command blocks or remove the NBT argument and hope for the best. Make sure to activate the command blocks!
You can then load the chunks (facing away from them if that helps) and hope the command blocks are able to resolve the situation.
Once you've cleared all of the entities, destroy the command blocks and use NBTExplorer to disable cheats if you didn't have them enabled before. It might also be wise to disable the source of the problem.
