God Damn Repackager

⚠️ ALPHA (0.2.0) This mod is in early testing. It uses a Mixin to modify Create's repackager core logic and has not yet undergone large-scale, long-term stability testing. Back up your world before using it. Bug reports are welcome on the project page.

The Problem

In vanilla Create 6.0+, when you place a large crafting order through the Stockkeeper for your crafter array (e.g. "craft 1000 iron blocks"), the entire order is processed by a single Repackager. Even if your input vault is surrounded by repackagers, only one of them does any work — the rest sit idle. A repackager emits only one package per second (20-tick animation cycle), so large orders take a very long time.

God Damn Repackager makes all repackagers attached to the same input vault share the work. N repackagers ≈ N× throughput.

Speed Comparison

Usage

No configuration required — works out of the box. Build your crafter array as usual:

Stockkeeper ──order──> Frogport ships materials ──> Input Vault (holds material packages)
                                                          ↓
                                            Multiple Repackagers (redstone block = always on)
                                                          ↓
                                            Packager (unwraps) → Mechanical Crafter → Output

As long as multiple repackagers are attached to the same input vault, this mod automatically parallelizes them. Repackagers must be placed against a Create Vault.

Installation

1. Minecraft 1.20.1 + Forge 47.x
2. Install Create 6.0.x (required dependency; tested with 6.0.8)
3. Drop the jar into .minecraft/mods/

Compatibility

• ✅ Tested: MC 1.20.1 + Forge 47.2.0 + Create 6.0.8
• ✅ Tested in modpack environments and on multiplayer servers alongside other mods — no conflicts
• ⚠️ Targets the Create 6.0.x logistics system only; not compatible with Create 0.5.1 and earlier
• ⚠️ Forge only (a Fabric port may come later)

Known Limitations

• The current implementation is "load-balanced snapshot allocation": at the moment a repackager assembles an order's packages, it decides who gets what based on current queue depth. This is sufficient for the vast majority of real cases; in extreme edge cases a repackager that goes idle after allocation won't "steal" work from another's queue.
• Repackagers must be attached to a Create Vault. Other containers (Crates, vanilla chests) are theoretically supported but not fully tested.

God Damn Repackager

⚠️ ALPHA This mod is in early testing. It uses a Mixin to modify Create's repackager core logic and has not yet undergone large-scale, long-term stability testing. Back up your world before using it. Bug reports are welcome on the project page.

ℹ️ If you used 0.2.0: 0.2.0 could cause "only some repackagers work after placing an order" (e.g. 6 of 9) in an existing world, requiring you to re-place the repackagers. Fixed in 0.2.1 — just upgrade, no re-placement needed. See Known Limitations.

God Damn Repackager makes all repackagers attached to the same input vault share the work. N repackagers ≈ N× throughput. Available for both Forge 1.20.1 and NeoForge 1.21.1.

Supported platforms & versions

This mod is maintained for two MC / loader combinations with identical functionality. Pick the jar that matches your setup.

Choose based on whether your pack runs Forge or NeoForge. If you're unsure: NeoForge 1.21.1 is recommended for new/single-player packs (more modern); stick with Forge 1.20.1 for existing saves or Forge-based packs.

Both builds are feature-identical: shared-package-pool parallelism (0.4.0) + partial repackaging (0.5.0 — start crafting as soon as any materials arrive, see below).

The Problem

In vanilla Create 6.0+, when you place a large crafting order through the Stockkeeper for your crafter array (e.g. "craft 1000 iron blocks"), the entire order is processed by a single Repackager.

As long as multiple repackagers are attached to the same input vault, this mod automatically parallelizes them. Repackagers must be placed against a Create Vault.

How it works

Instead of each repackager hoarding an entire order in its own send queue, 0.4.0 uses a per-vault shared package pool (stored in the world save):

• Deposit — when a repackager finishes assembling an order's packages, the whole batch goes into the shared pool keyed by the vault it serves, rather than into its own private queue.
• Poll on demand — every tick, each idle repackager pulls one package out of the pool into its own queue, then ships it as normal. N repackagers genuinely ship N packages/second.
• Inherently dynamic — because each repackager pulls work on demand, a stalled repackager (its downstream clogged) simply stops polling and its work is naturally picked up by idle siblings. No separate rebalance layer is needed.

Partial repackaging (new in 0.5.0): vanilla repackagers wait until ALL of an order's material fragments have arrived before doing anything (all-or-nothing). Fragments trickle in over the transport network, so large orders waste a long "waiting for the last piece" window. 0.5.0 lets repackagers start as soon as the arrived fragments afford at least one craft: available materials are crafted and shipped immediately, and each newly arrived batch continues the order until it's done. Materials are conserved end-to-end — unused leftovers are held in the world save and drop in full if the vault is broken.

Note on breaking blocks (0.4.0): the shared pool is saved with the world, independent of any block. Breaking a repackager does not drop the packages still in the pool — they're kept safely in the save, and placing the repackager back resumes processing (nothing is lost). Only when the vault itself is destroyed (block broken or wrench-removed) are that vault's pooled packages dropped as item entities. Reshaping a vault (adding/removing blocks to change its shape) does not drop the pool either — the pool migrates to the new shape automatically and repackagers keep processing. Repackagers respect vanilla Create redstone: they only work when powered.

Installation

Installation is identical for both builds — only the jar and Create version differ:

1. Install the matching Minecraft + loader combo (see Supported platforms above)
2. Install Create 6.0.x (required dependency; version per the table above)
3. Drop the matching goddamnrepackager-*.jar into .minecraft/mods/
4. Launch the game

Upgrading from 0.2.0? Just replace the jar. 0.2.0 used to require re-placing repackagers in an existing world; 0.2.1 fixed this — no re-placement needed after upgrade. See Known Limitations.

Upgrading from 0.3.x / 0.4.x? Just replace the jar — no re-placement needed, in-flight orders are unaffected. 0.5.0 adds partial repackaging on top of the shared pool (start crafting as soon as any materials arrive); you benefit automatically with zero setup.

Compatibility

• ✅ Tested:
  • MC 1.20.1 + Forge 47.2.0 + Create 6.0.8
  • MC 1.21.1 + NeoForge 21.1.x + Create 6.0.10
  • ✅ Tested in modpack environments and on multiplayer servers alongside other mods — no conflicts
  • ⚠️ Targets the Create 6.0.x logistics system only; not compatible with Create 0.5.1 and earlier
  • ⚠️ Forge 1.20.1 and NeoForge 1.21.1 are maintained independently with identical features; a Fabric port may come later

Known Limitations

• Re-place repackagers after installing into an existing world. (Fixed in 0.2.1) 0.2.0 could cause "only some repackagers work after placing an order" (e.g. 6 of 9) in a world that already existed — far more often on multiplayer servers than in fresh single-player worlds. Cause: 0.2.0 identified sibling repackagers by the identity (==) of the Forge capability instance they cached, which is rebuilt whenever the vault's capability is invalidated, so repackagers placed before the mod existed could hold caches pointing at different generations and fail the check. 0.2.1 fix: siblings are now matched by Create's InventoryIdentifier value equality (for vaults: a Bounds(BoundingBox) record comparing only the multiblock's corner coordinates), which is stable across capability rebuilds. Upgrading to 0.2.1 resolves this — no re-placement needed. (Technical detail in TECHNICAL.md §3.7.)
• The current implementation is "load-balanced snapshot allocation"... (0.3.0 added dynamic rebalancing on top; 0.4.0 replaced both with a shared package pool) — 0.4.0 deposits each assembled batch into a per-vault shared pool that idle repackagers poll from on demand, giving the same parallel/dynamic-balancing effect with simpler logic.
• Breaking a repackager does NOT drop the shared pool (0.4.0). The pool is saved with the world, not tied to the block. Breaking a repackager only drops the single package it was mid-shipping (heldBox); packages still in the pool stay in the save and resume when the repackager is replaced — nothing is lost. Only destroying the vault itself (breaking a block or wrench-removing) drops that vault's pooled packages. Reshaping a vault (adding/removing blocks) does NOT drop — the pool migrates to the new shape and processing continues.
• An order being progressively crafted needs at least one powered repackager (0.5.0). Once an order is "taken over" (partial repackaging has begun), it needs at least one redstone-powered repackager on the vault to keep progressing. Removing all repackagers or cutting their power pauses the order — unused materials stay safely in the world save (and drop if the vault is broken); place a repackager back and power it to resume. Orders without crafting recipes (plain item orders) are never taken over and behave exactly like vanilla.
• Repackagers must be attached to a Create Vault. Other containers (Crates, vanilla chests) are theoretically supported but not fully tested.
