Unofficial port of Carpet Fixes to Minecraft 1.21.11.

Carpet Fixes is a Fabric Carpet extension that fixes as many vanilla Minecraft bugs as possible — redstone update order, dupes, mob behaviour, pistons, observers, rails, explosions and much more. Every fix is a toggleable rule.

This build ports it to 1.21.11, based on tomalbrc's 1.21 fork. Tested in-game (loads with no mixin errors).

⚙️ Requirements

  • Minecraft 1.21.11
  • Fabric Loader ≥ 0.16.9
  • Fabric Carpet 1.21.11-1.4.193+v251211 or newer — required
  • Java 21
  • Fabric API is not required
  • conditional-mixin is bundled (jar-in-jar)

📦 Installation

  1. Install Fabric Loader for 1.21.11.
  2. Drop into mods/:
    • fabric-carpet for 1.21.11
    • this jar
  3. Configure rules in game with /carpet-fixes <rule> true|false (the mod has its own command — NOT /carpet). Full rule list with descriptions: see RULES.md / RULES-EN.md in the repo.

Works in singleplayer & multiplayer.

✅ What's included

246 fixes active — redstone update order, dupe fixes, mob/entity behaviour, blocks, pistons, observers, rails, explosions (including the correct TNT exposure calc — incorrectExplosionExposureFix), spawn chunks staying loaded, and more.

Restored & tested in 1.18.1-port: creeper portal fuse, blue wither skulls saved, brewing time on unload, bubble column, /data on players.

❌ What's disabled

A handful of fixes are incompatible with 1.21.11 without a full rewrite, or are now redundant (Mojang fixed the bug in vanilla):

  • Custom redstone neighbour-updater (useCustomRedstoneUpdates, optimizedNeighborUpdater, reIntroduceInstantBlockUpdates) — neighbour-update system reworked (WireOrientation / ChainRestrictedNeighborUpdater).
  • Explosion world-border (explosionsBypassWorldBorderFix) — Explosion became an interface and ExplosionImpl was restructured.
  • Entity block-collision / x8-portal — collision reworked to a tickBlockCollision(from, to) queue (vanilla likely fixed it).
  • RecipeManager optimization — recipe API reworked (Lithium covers it anyway).
  • palette data-corruption — palettes no longer hold a resize listener → bug can't happen.
  • ChorusFruit / Boat fall damage, Warden eats armor, DaylightDetector placement — classes/methods removed or made final.
  • Mob conversion data transfer — vanilla's EntityConversionContext handles it now.
  • debug tools & server-toggle rules.

⚠️ Note

The mixin config uses defaultRequire = 0: if a fix can't apply in some rare, untested path, it is silently skipped instead of crashing the server.
