What is Feature NBT Deadlock Be Gone?
2 parts
Feature NBT Deadlock Be Gone has one job: it fixes a Minecraft 1.18 worldgen bug (MC-246262) that can freeze your game. You never craft it, place it or open a menu for it. It sits in the background and keeps world generation from locking up.[1]
What the bug is
When a structure built from NBT data is placed during worldgen, and it replaces a block entity, the game can deadlock. Spawners, chests, lecterns, beds and signs are all examples. When that happens the game locks up and freezes, and ticks stop running.[1]
The cause is that the method which places the build's blocks isn't worldgen safe, because it uses the wrong world object internally. The mod fixes this by skipping the calls to those unsafe methods whenever the world passed into the NBT placing method is a WorldGenRegion.[1]
Who it is for
Everyone who explores this pack, though you'll only notice it if it's missing. The bug can show up more often with mods that add their own structures, so the author recommends keeping this mod installed as a precaution.[1]
The bug only exists in 1.18.x. It doesn't occur in 1.17.x and below, and it is fixed in 1.19 and above. The pack ships the Forge build, version 2.0.0+1.18.2.[1][2]
Unverified The sources don't show any quests, progression steps or ATM Star path involvement for this mod, so it isn't tied to a particular stage of the pack.
How do you get started with Feature NBT Deadlock Be Gone?
2 parts
Good news: there's nothing to craft here. This mod is a bug fix, and its only goal is to stop a worldgen freeze that exists only in Minecraft 1.18.x. You don't need to build, unlock or set up anything for it to do its job.[1]
What it does for you
The bug hits when an NBT build is placed during world generation and it replaces a block entity, such as a spawner, chest, lectern, bed or sign. When that happens the game can deadlock: it locks up and freezes, and ticks stop running.[1]
The cause is that the method placing the build's blocks isn't worldgen safe, because it uses the wrong world object internally. The mod fixes this by skipping those unsafe calls whenever the world passed into the NBT placing method is a WorldGenRegion.[1]
Why it's worth having in a modpack
Mods that add their own structures can trigger this bug more often, so keeping the fix installed is a sensible precaution. The bug doesn't occur in 1.17.x and below, and it's fixed in 1.19 and above.[1]
Unverified No quests, crafting recipes, items or config options for this mod could be confirmed from the available sources, so there are no first steps to follow beyond leaving it installed.
How does Feature NBT Deadlock Be Gone work?
2 parts
This one is different from most mods on the wiki. Feature NBT Deadlock Be Gone has no machines, multiblocks, power, fluids or item automation to learn. According to its project page, its sole goal is to fix one Minecraft bug, tracked as MC-246262, which only exists in 1.18.[1]
The bug it fixes
The bug shows up when a structure built from NBT data is placed into the world during world generation and it replaces a block entity of any kind. Spawners, chests, lecterns, beds and signs are all examples. When that happens the game can deadlock: it locks up and freezes, and ticks stop running.[1]
How the fix works
The cause is that the method used to place the build's blocks is not safe for world generation, because it uses the wrong world object internally. The mod fixes this by skipping the calls to those unsafe methods whenever the world passed into the NBT placing method is a WorldGenRegion class.[1]
You don't have to do anything for this to work. The page describes no items, blocks, machines or settings to interact with.[1]
Unverified Nothing in the available material covers pack-specific changes, config options, quests or recipes for this mod, or which exact version of it the pack ships, so none of that is described here.
What changed in Feature NBT Deadlock Be Gone between versions?
There isn't much history to cover for Feature NBT Deadlock Be Gone, but here is what is confirmed. All the Mods - Gravitas 4.0 ships version 2.0.0+1.18.2 of the mod. It has been in the pack since All the Mods - Gravitas 1.1 or earlier, so it's a long-standing part of the modpack.[2]
The mod's own changelog is very short. Its only entry is the first release, listed under Misc, and it says just "First release." That is the only change the changelog records.[3]
Unverified The sources here include no pack changelog entries for this mod. The pack's own changelogs are where any Gravitas release that changed, added or removed it would be recorded, but they are not shown here, so that part of its history is unverified.
