Long NBT Killer Mod FAQ

6 questions players actually ask, answered.

What does the Long NBT Killer Mod do?

It replaces the exception Minecraft throws when it encounters a compound or list NBT tag deeper than 512 with a harmless log warning, allowing the game to continue loading the save.

What happens in vanilla Minecraft when a save contains an NBT tag with a depth greater than 512?

Minecraft throws an exception and refuses to load the save.

Does the mod prevent the save from loading when deep NBT is present?

No, it lets the game go ahead instead of refusing to load the save.

What should I do after seeing the mod's warning in the log?

You may check your save with an NBT editor, since a compound or list tag deeper than 512 is abnormal.

Is a compound or list NBT tag with a depth greater than 512 considered normal?

No, it is abnormal, which is why checking the save with an NBT editor is recommended after the warning.

Does the mod remove the deep NBT tag from the save?

No, it only replaces the exception with a log warning and lets the game continue; the abnormal tag itself remains in the save.
